Test Report of Thursday 14.06.2007

ElQA
- RQD.A78 and RQF.A78 circuits released by ElQA. Circuits OK for powering as soon as QPS gives green light.
- MBA and MBB lines tested OK up to 1 kV with all instrumentation connected. Circuit OK for QPS IST

RD2.L8, RQ4.L8 and its correctors
- Powered to nominal (6000 A) during the whole morning. Ramped down to beam operational current (5980 A) in the begining of the afternoon.
- Keeping RD2.L8 at operational current, the five Q4 correctors available were ramped to nominal current (72 A) RQ4.L8 is powered acording to the procedure attached (see slide) up to 3.6 kA and 2.95 kA in apertures 1 and 2 respectively. No quench was observed.
- Pushing for the quench: With D2 at 6kA, aperture 1 of Q4 at 3610 and four correctors at nominal
  - Ramp up from 2950A to 3610 at 1 A/s - OK
  - Ramp down from 3610A to 2950A at 5 A/s -OK
  - Ramp up from 2950A to 3610A at 10 A/s -OK
  - Ramp down from 3610A to 2950 at 10 A/s - OK
  - Ramp up from 2950A to 3610A at 10 A/s - OK
- Magnet still doesnt quench, so we go on:
  - Ramp up Aperture B1 and B2 from 3610A to 2200A at 10 A/s - OK
  - Ramp up Aperture B2 from 2200A to 3610A at 10 A/s - OK

RQ5.L8 and its correctors
- Calibration tests in all the converters

600 A Circuits
- Very useful data was obtained during the morning on the RQ6.R7 quench detectors
- Generation and analysis of the QPS data advances in parallel with PCC tests for the available 600A circuits in the DFBAO

60 A type test performed but not finished. Half a day more needed.

Planning for Friday 15.06.2007

RQF.A78 and RQD.A78
- Wait for green light from QPS to go ahead with PIC tests. All heaters and quench loop worked OK, 'Switch Open Failure' functionality to be corrected.
- PIC1 for both circuits as soon as QPS gives green light.
- AB/PO will use the characterisation values obtained during ElQA to avoid the connection of a 120A converter for PCC.
- The DC cables will be connected to the leads once PIC1 is completed.

RB.A78
- QPS IST to start today. They will take around 2 days.

600A Circuits in the DFBAO
- PCC will continue for the circuits available. QPS will take proffit of them to obtain the needed data for improving the filtering of the detector noise.
- PIC2 for the circuits in which PCC is completed
- AB/PO will do some measurements after PIC2 (below 20A)

Matching Section ML8
- 8-hour heat run with all the circuits in the matching section at nominal current
- Squeezing tests for RQ5.L8 and RQ4.L8 can be carried out in parallel

60 A type test will start after QPS IST for RQF and RQD are completed.

Cryo-instrumentation
- The time needed by QPS to implement the corrections in the 600A quench detector software will be used to test the electronica cards from cryo damaged during the ElQA tests.

Going-on Activities

SSS Replacement

Inner Triplets:
- Left 1: closed, being leak tested
- Right 8: closed, being leak tested

Electrical non-conformities on instrumentation cables of the power converters will be closed by the end of the week.

The procedure for cleaning the DFBXH is currently being completed. In principle, the instrumentation wont have to be removed.

Planned activities

PIC-PC interface test - Wk 43
Room temperature vacuum and collimator works (wks 43-46), bake-out (wks 47 -48)
ATLAS-RP cable installation - Wks 48-49
TS/EL:

From Pressure Tests to Cooldown - Point 8 - Monday 09.10.2007

Sector 8-1

Inner Triplets
- Right 8: the leak has been located in line C', precisely on a weld in the middle of the flexible. It is currently being replaced by the US collaborators. Once it is corrected and the works in the SSS completed, the inner triplet will be pressurised again for testing. It should be sufficient for this test to have the C' line in the SSS welded, however it is not sure that only one line can be pressurised without affecting the other lines, hence most likely the test will be carried out at the end of the SSS works (wk 47).
- Left 1: inner triplet closed and being leak-tested.
SSS Q17R8
- The replacement of the SSS started this week and will last till wk 46.
- Local electrical tests will progress in parallel with the assembly of the SSS.
MB1158
- The diode has been cleaned up. A continuity test will be done before closure beginning of next week. The final validation cannot be done before the TP4-A before the flushing.
DFBAs repairs
- A latest date for taking a decission about repairing or not the DFBAs has to be set for not jeopardizing the starting date of the flushing.
- Paolo reminds that the time used for reparing the DFBAs will be different for each sector due to the different configurations.
ElQA
- TP4-A is planned for week 47, just before the flushing.
- Low voltage continuity tests of the dipole lines will be carried ut during the SSS replacement between the DFBAA and C18R8
- The non-conformities being corrected by INEO this week will be re-checked once they are closed.
AUG Test
- The yearly AUG test for the whole Point 8 is planned for October 19. HCC will study how can we get the maximum profit from it.
A4L1
- Vacuum mechanical works will start on week 43 and will last till week 47.
- Collimator to be installed week 44.
- Neg-activation weeks 48 and 49 (overlaps with one week of flushing)

The following circuits are affected by a problem in a QPS card: RSF1.A78B1 RSD1.A78B1 RSD1.A78B2

RQ6.R7B1/B2 were tested but tripped due to QPS threshold. Reiner needs to increase the threshold there. In agreement with MPP, it has been decided to raise their threshold to 50 mV.

Activity for tomorrow, Thursday 5th.

condamnation of all coverters of point 7, to allow ElQA to start their tests there (RQ6, in DFBMH, is on the same electrical depart as other circuits of DFBAN);
Reiner will work on the QPS system for RSD1.A78B1/B2 and RSF1.A78B1 tomorrow morning around 9.00 (change of detection card required); as soon as he finishes, those circuits will be powered up to PCS4;
as soon as the three circuits above are over, condamnation of all converters of DFBAO;
as soon as Reiner finishes the intervention on RQ6 (probably early afternoon), the corresponding converters will be de-condamned and RQ6 powered for PCS4 (THIS HAS TO BE DONE IN ACCORDANCE WITH ElQA FOR WHAT MENTIONED ABOVE ON THE SAME ELECTRICAL DEPART!!!); the converters will be condamned again right after.

ElQA activity:
- matching section to be completed;
- RB to qualify (after disconnection by Philip Denis of leads in point 7)
- RQF/D qualification
- 60 A COC

Cooldown Sector 78

We are now in the last week before the warm-up of sector 78 for the repair and connection of the inner triplet magnets and some consolidation work which is expected to last six weeks.

During the past week, the commissioning of sector 78 has continued on several fronts: the main magnet circuits, the 600 A corrector circuits, the 60A dipole correctors as well as the matching section magnets. This activity was made possible thanks to the very stable operation of the cryogenic system and of the utilities almost throughout the week. Unfortunately starting from Thursday morning two independent faults (return heater, 24V power supply) in the cryogenic system compromised the powering tests at 1.9K for the rest of the week.

After the two quadrupole circuits, which were both powered to 6.5 kA, the dipole circuit was successfully taken to 2 kA on Wednesday (June 27th) morning. The first cycle is shown below. This cycle ends with a discharge of the circuit in the dump resistor.

The in depth analysis of the data collected during these runs is ongoing to validate the correct operation of all the equipment.

The commissioning of the 600A circuit could finally start after the careful tuning of the quench detection system and the successful interlock test with the power converters connected to the magnets. The quench detection system is set to run with very low detection thresholds. The tests on these circuits are aimed at validating the intermagnet splices some of which could have been executed not to the required standards. These tests will continue this week.

Although not at full thrust, the commissioning of the 60 A orbit corrector circuits is progressing. In addition to all this, detailed studies on many circuits were performed to better identify the powering parameters of these circuits.

Studies to better understand the coupling between the Q4 and the D2 magnets did not succeed to reproduce the phenomenon which was initially observed despite all the efforts.

The preparation for the cool down of sector 45 is well advanced: the electrical quality assurance identified and localized a short in the dipole circuit which was very quickly repaired. A mechanical non conformity was also detected during the flushing: it concerned the swap of two lines in the interconnect between the low and high current module of the DFBAH. This was also quickly repaired and the conditioning of the lines continued over the weekend.

The puppets of the Joule-Thomson CV910 were also replaced and the cooldown is expected to start on Wednesday July 4th.

  - PM problem noted: the data, although complete, does not display correctly in the PM viewer. Sandrine will look at data manually and Adriaan will correct the problem
  - after a discharge request from the PC, the PC fault and discharge request signals arrive out of sequence. According to Valerie this is understood (due to cable delays)
  - QPS_OK does not take into account the switches status allowing powering of the magnets with the switches open
- Connection of the DC cables to the current leads has not happened yet. Will be done tomorrow at 7:30

RB.A78
- QPS IST. All heaters charged (2 out of 700 needed intervention) Discharging started at 16:45 (will need 3-4hours to complete)

Powering Tests Sector 78 - Report 08/06/2007

Test Report of Friday 08/06/2007

RQ6.R7B1 and RQ6.R7B2
- PCS.1: Sinus excitation at 1 and 10 mHz OK, the detector tripped for 200 mHz and could not be tested up to 1 Hz as expected. Hoewever, the test is considered as OK for the QPS experts since they gather enough information about the circuit and the dectector performance - TEST OK
- PCS.2 (Extraction at 50 A): Detector tripped for ramp rates of 0.5, 0.4 and 0.3 A/s, it worked OK at 0.25 A/s. There was a problem in the transmission of the Post Mortem data, which did not reach the server the first time. The problem was fixed and no data was lost. The issue has not been understood yet - TEST OK
- PCS.3 (Extraction at 100 A): Test OK
- PCS.4 (Plateu at 200A): The detector tripped while the current was reaching the plateau due to the very well known issue with the d2I/dt2. Energy extraction worked ok - TEST NOT OK.

80-120A Correctors of Q4-Q5:
- PNO.4 (Slow Power Abort from PIC): Battery of seven circuits test together - Test OK
- PNO.2 (Full current bi-polar cycle) repeated after the meeting - Test OK

Powering Tests Sector 78 - Report 07/07/2007

Test Report of Thursday 07/06/2007

RQ6.R7:
- PIC2 tests were blocked due to a damaged electronic card in the QPS controller which affected the creation of Post-Mortem data and the proper generation of interlock signals. The problem is understood now and the card changed. PIC2 will be completed today after the evening meeting.

RD2.L8:
- The circuit was powered and the heater discharged at 200 A in order to check the new instrumentation implemented by AT/MEL. The system still needs some hardware work. The protection system is working properly. RD2.L8 stays blocked till Monday since priority is given to RQ6.
- Antonio Perin presented the non-conformity in the internal cabling of the RD2 and RQ4 circuits in the DFBMA.L2 and DFBMA.L8 which may be the cause of the triple quench event of last week in the matching section.

RQ5.L8 and RQ4.L8
- Liberated now for further powering after the Powering Subsector OFF functionality has been disabled in the ML8 powering subsector.
- SPA from PIC in RQ4.L8 at nominal current: Test OK
- SPA from PIC in RQ5.L8 at nominal current: Test OK

80-120A correctors in Q4 and Q5:
- Ramped all together after the meeting at nominal current and kept there for a couple of hours.

ElQA
- MBB line to be retested with all the instrumentation connected.
- MBA line: the test with the cryogening system and one QPS rack disconnected could not start today since the boiling test in the DFBAN is taking longer than expected. If the test fails, it will be repeated with 50% of the QPS racks in the MBB line (38 units) disconnected. If the test is still failing, all the QPS racks will be disconnected.

Planning for Friday 08/06/2007

RQ6.R7B1 and RQ6.R7B2
- PCS.1-PCS.4 tests (Sinus at +/-10A, energy discharge at 50, 100 and 200A) from the CCC
- Upgrade of the controller software after the test.

RQ4.L8 and RQ5.L8
- Squeezing tests if possible.

80-120A correctors Q4 and Q5:
- PNO.4 test in battery for the seven circuits available.

Powreing Test Sector 7-8 - Report 06/06/07

Test Report Wednesday 06/06/2007

RQ4.L8
- Manual Squeezing test (PSQ). Test OK. (The test will be considered as fully passed only once automatic function is used)
- When Squeezing was finished, the magnet was ramped to nominal current (3610 A) and kept there for "endurance test"; after one hour, the B2 converter tripped and a FPA was initiated: analysis of the PM signals was indicating an external interlock alarm - red emergency button pressed. Nobody was in the area at that moment.
- The two converters were ramped back to nominal and kept there; after three hours, the same trip as before was experienced on B2 and the FPA initiated. The circuit was blocked for powering.
- Further investigations showed that the two trips were provoked by a mispositioned pin in the connector on the emergency red button. Already fixed by PO.

RQ6.R7B1 and RQ6.R7B2
- PCC completed by PO and QPS in the tunnel of point 7.
- PIC2 CRYO-OK passed on RQ6.R7B1, RQ6.R7B2, RCBH6.R7B2 and RCBV6.R7B1.
- Remaining steps of PIC2 passed on RCBH6.R7B2. Not possible to continue with the others due to a communication problem with QPS detectors; a manual reset in UA83 is needed.

Planning for Thursday 07/06/2007

RQ6.R7B1 and RQ6.R7B2
- Complete PIC2 on the two 600 A circuits and the corrector RCBV6.R7B1
- PCS.1, PCS.2, PCS.3, PCS.4 (Ramp rate 0.2-0.5 A/s)

600 A correctors
- Cable connection on the circuits released by ElQA (after verification by PO of the condemnation of those converters)

80 A correctors of Q4 and Q5: "Endurance test" after Reiner's intervention

ElQA tests:
- Further investigations on RB circuit/instrumentation

ML8: once D2 is available, special cycle with D2, Q4 and Q5.

Powering of RQ4.L8 and RQ5.L8 to validate the FGC software update

Boil-off tests on DFBAN in the morning.

Powering Test Sector 78 - Evening Report 05/06/2007

Test Report Tuesday 05/06/2007

RQ4.L8
- Special tests carried out by AB/PO from the tunnel in the converter in order to further study the fault in the FWD seen yesterday during the Fast Power Abort test (PNO.9)
- While trying to ramp the converter up during the decay after a provoked fast power abort, the quench detector tripped and the quench heaters were fired. RQ5.L8 was going through the squeezing tests at the moment of the Q4 sporious quench, hence it performed a Fast Power Abort and its quench detector did not trip although it was at 3 kA.
- Fast Power Abort from PIC Test repeated after diode was repaired (PNO.9). Test OK.

RQ5.L8
- Manual Squeezing tests (PSQ). Test OK. It will not be considered as fully passed till it is done with the automatic function.

RQ6.R7B1 and RQ6.R7B2
- PCS test up to +10 A OK. The quench detector performed OK at this current level. There is a problem in the supervision that is being fixed. The transfer functions measured by AB/PO match very well the ones measured during ElQA tests.
- Due to a missunderstanding with MPP and HCC, the circuit was powered up to 60A in order to check the crowbar. At 53 A, as expected, the QPS provoked a FPA that opened the switches. The procedure has to be reviewed since, so far, powering above 10 A is not allowed before carrying out PIC2. HCC will find an agreement by tomorrow between Mr Circuit, AB/PO and MPP.

ElQA RB.A78
- At 600 V, with all the DFB instrumentation except the lead heaters disconnected, the resistance of the leads was 346 and 260 Ohms for 5 minutes which is a very promising result. Tests will continue tomorrow when 1.9 K are expected.

Planning for Tomorrow 06/06/2007

RQ4.L8
- Powering at nominal plateau for some hours
- If functions are available: Squeezing test

RQ5.L8
- After modification in the quench detector: Fast Power Abort at nominal current (PNO.9)
- If functions are available: Squeezing test

RD2.L8
- Once new instrumentation is operational: Power to nominal current step by step.

ElQA
- Tests up to 1.9 V in RB.A78

Powering Tests Sector 78 - Afternoon Meeting 04/06/2007

Test Report Monday 04/06/2007

RQ5.L8: Powered up to nominal. During the first trial, the quench detector triggered at 27A. The magnet was powered at its nominal current for 4 hours. Tests successful. MPP is asked to give permission to increase the detection threshold to 100 mV (nominal) to carry out the Fast Power Abort test (PNO.9)

RQ4.L8:
- Powered up to 250 A while RQ5.L8 was at nominal in order to check the integrity of the circuit. Test OK.
- Once RQ5.L8 test was completed and with the agreement of MPP, RQ4.L8 was powered at different current levels up to its nominal current (250, 600, 2000 and 3610 A) and kept there for 20 minutes. Test OK.
- Squeezing tests (PSQ). Test OK.
- Fast Power Abort from PIC at nominal current (PNO.9). The circuit did not quench, however, AB/PO considers the test as failed due to the FWD circuit creating a fault. Under investigation. Test NOT OK.

RQ6.R7B1 and RQ6.R7B2
- PCC Circuit Config tests going on. Some correction in the quench detectors have to be carried out. The noise level in the detector looks promising. Tests will continue tomorrow Tuesday.

RD2.R8
- Amalia has analysed previous quenches in this magnet. None of them showed any effect on the level and temperatures in the DFBMA, hence they can conclude that the quench ocurred in the DFBMA but they cannot confirm its cause yet.
- AB/CO has completed the interlock and circuit synoptics modifications needed for the new instrumentation in D2. Reiner will get the hardwire ready as soon as he finishes the correction in Q6.

Boil-off Tests
- DFBAO Low Current Module: test completed, further studies need to be done in the He level gauges
- DFBAO High Current Module: Test going out. They should be completed this evening. Promising results so far.
- DFBAN being refilled, the calibration data is being checked.

Planning for Tuesday (05/06/2007)

RQ5.L8:
- Squeezing Tests (PSQ)

RQ4.L8:
- Run at nominal current for some hours
- Repeat PNO.9 (FPA) if required by AB/PO

RQ4.L8 & RQ5.L8 & Correctors
- Powering at nominal current together (?)

ElQA RB.A78
- Tests will be restarted tomorrow Tuesday. First priority activity.

60A Converter Type test
- If possible in coordination with the ElQA.

Cooldown Sector 78

The commissioning programme on Q4, Q5, D2 and the associated correctors continued during this week. While the Q4, Q5 and D2 commissioning was completed, the commissioning of the 120 A correctors associated to these magnets could not be completed: some additional tuning of the software in the FGC remains to be done.

Yesterday (Thursday May30th) Q4, Q5, D2 were taken together to nominal current. At about 80% of the ramp, D2 quenched (5268 A). As expected, this caused the shutdown of the converters in the matching section and during the ramp down Q4 and Q5 also quenched. The data of this event is still being analysed.

The Electrical Quality Assurance team qualified the focusing and the defocusing quadrupole circuits and the matching section quadrupole Q6 at Point 7.

All the DFBs of the sector have been equipped with dry-air bags to ensure no condensation forms on the current leads and their chimneys.

Unfortunately, on Friday (June 1st) morning, the safety chain of cabinet was accidentally broken and the sector was disconnected from the pumping group. The cryo team is now busy recovering the situation to re-establish nominal temperature on the magnets for Monday morning.

Powering Tests 7-8 - Evening Meeting 01/06/2007

ACTIVITY OF FRIDAY

* Triple quench in the matching section (Q5, Q4 and D2) is still under investigation. The current leads have been excluded as possible quench origin. New hardware will be implemented on Monday in order to better analyse the future events. In principle the quench in Q4 was not induced by the previous quench in D2, the delay is too short for that.

* The circuits in the DFBMH have been released by ElQA and QPS.

* 1.9K in the arc are not granted for Monday

PLAN FOR TODAY MONDAY

TEAM 1 - RR77 (& CCC)

* Connection of the four 600A current leads of the DFBMH (RQ6.R7B1 and RQ6.R7B2).

* PCC-Circuit Configuration tests in the circuits of DFBMH. Remark: the PC Permit signal from PIC will have to forced since the DFBMH belongs to the A78 powering subsector

* PIC2 in the DFBMH circuits (CCC)

TEAM 2 - CCC

* Powering of RQ5.L8 and its correctors to nominal current in intermidiate steps. Run for some hours at nominal current for validating the splices. If the test is successful the detection threshold of its quench detector will be risen to its normal operational value (100 mV)

ElQA

* If cryogenic conditions are recovered (2.1 K) ElQA of the RB.A78 circuit will continue. First, all the electronics of the DFBAs will be disconnected. If the test still fails the QPS electronics in the tunnel will be disconnected. Reiner ask for one hour advice for carrying out the disconnection.

COMPLETED ON 30/05/07

CORRECTOR CIRCUITS (Q4,Q5)	RCBYVS4.L8B1; RCBYVS4.L8B2; RCBYV4.L8B1 went through PNO.1, PNO.2 and partially PNO.3
	RCBYVS4.L8B2 had a training quench during PNO.2
	RCBCH5.L8B1; RCBCV5.L8B2; RCBYH4.L8B2; RCBYHS4.L8B1 went partially through PNO.3
RQ4.L8	Unbalanced ramp up to nominal and unbalanced quench (PNO.8c) Third trial for the unbalanced cycle up to nominal: B1 and B2 got to nominal current. In the ramp down of B1, due to a too the fast negative slope the converter tripped. B2 slow power abort commanded by PIC. (Since B2 reached nominal current, there is not need to repeat the quench at nominal current in both apertures, PNO.7a is considered OK)
	Provoked unbalanced quench with (B1 at nominal). PNO.8c OK.
	Current cycle up to nominal PNO.9
RQ5.L8	Provoked unbalanced quench with (B1 at nominal). Ramp down from nominal this time worked OK. PNO.8c OK.

Powering Tests - Sector 7-8 - 30/05/2007

Yesterday was devoted to perform tests on RD2.L8 and RQ4.L8

- RD2.L8 has been successfully commissioned up to PNO.8d (Current cycle up to nominal current)
- Missing tests for RD2.L8: Fast Power Abort from PIC (PNO.9). The detection threshold needs to be modified. Possibly done while powering at unison (like PNO.9 for RQ5)
- RQ4.L8:
  - - Unbalanced cycle up to nominal (3610 A) for B1 and 2000 A for B2. While ramping B1 converter tripped. The attempt of PO expert to recover control made the quench detector trip (same problem as last week)
    - Second trial of unbalanced cycle up to nominal: with B1 at nominal current and B2 ramping up to nominal, the latter quenched at 3590 A. Test failed.

Proposal for the activity of today (30/05/2007)

Complete P2N of all the 120-80A correctors of Q4 and Q5.
Continue P2N of RQ4.L8. Two options: * Unbalanced ramp up and quench with both apertures at nominal current (PNO.7a) or/and * Unbalanced cycle and quench with one aperture at nominal and the other at 50%.

ElQA activities: Morning: * Full qualification of the 3 circuits selected on DFBAN * TFM on circuits powered via DFBMH * preparation for the HV qualification of the 600A circuits Afternoon * HV qualification on 600 A circuits powered via DFBAO

QPS: Interlock tests .

The following tests have been executed on D2 (MANUAL execution, due to change in procedure):

PIC2 (SEQUENCER execution); test successful;
PLI1: ramp to 350 A with 10 A/s ramp rate, we stayed on the plateau 4 min and then provoked a FPA; test successful;
PLI2: ramp to 350 A with 10 A/s ramp rate, then ramp to 1000 A with 10 A/s, and quench driven by QPS, generating an artificial quench signal from one current lead detector; the test was successful;
PNO: during the first attempt to ramp to 3000 A, the power converter went to ‘faults’ and produced a FPA when reaching 1008 A; investigations of PO showed that a hardware limitation was present. The second attempt was successful:
- Ramp to 350 A with 10 A/s ramp rate;
- Continue ramping to 3000 A; plateau of 4 min;
- Continue ramping to 6000 A (nominal current); plateau of 30 min to check voltage drift;
- Provoked quench at nominal current.

Proposal for the activity of next week.

Continue powering Q4 and D2
Continue powering the correctors (4 circuits have already passed the first 2 steps, three more are available).
Possible powering of the whole matching section.
Powering of the arc 60 A orbit correctors, according to humidity conditions.

Continue installation of plastic bags on DFBAN and DFBMH.
Check the status of condensation of the 13kA leads of DFBAO which have copper laminations and no plastic bags; check the status of the 6kA lead of DFBMA which has copper laminations and no plastic bags.
Installation of ventilators on the 60 A orbit correctors leads.

Powering tests in Sector 7-8: activity of Thursday 24/05.

The day was fully devoted to perform tests on Q4, which had experienced an unexpected quench at 300 A on Monday (after ramping at 600 A).

The following tests have been executed on Q4 (MANUAL execution, due to change in procedure):

ramp to 600 A with 5 A/s and quench driven by QPS, generating an artificial quench signal from one current lead detector; the test was successful;
ramp of B1 power converter to nominal current (3610 A) with 10 A/s ramp rate and simultaneous ramp of B2 power converter to 2000 A with nearly 5 A/s (unbalanced configuration):
- when B1 current reached 1025 A, its reference current went anormally down to 0;
- later analysis showed that a fault was sent from the converter and a consequent FPA was started;
- PO attempt to get control of B2 power converter, to ramp it down contemporarily to 0, provoked a sudden voltage peak in B1, which initiated a quench;
at 11.48 (according to PIC supervision) a power cut occured on the general services of UA83, which eventually provoked the loss of controls on cryogenics and lead heating system;
after waiting for the good cryo conditions to be recovered, and in agreement with PO, QPS and MPP experts, we decided to ramp again Q4 with the same unbalanced cycle:
- B1 at 3610 A with 10 A/s ramp rate and B2 to 2000 A with a nearly 5 A/s ramp rate;the test was successful and NO quench was activated;
- while ramping B2 power converter to the same current as B1 (the idea was to stay on plateau for half an hour and then provoke a quench), and with a current in B2 of 2900 A, a quench generated; preliminary analysis indicated that it was started in B1, possibly due to electromagnetic coupling (this configuration has never been tested before).
end of the tests due to long recovery time.

Proposal for the activity of tomorrow.

Continue powering Q4 and D2.

Continue installation of plastic bags on 600 A current leads.
Lower the temperature on the 13 kA leads to check the absence of condensation with AT/MEL copper laminations.

ElQA on the selected circuits: list will be provided during the morning.

Sector 7-8 cooldown

After becoming the first magnet at 4.5K and in the kA range to be powered last week, the Q5 matching section quadrupole (MQM) left of Point 8 became the first one to reach nominal current on May 23 @ 15:04:28. The two apertures of the magnet were then powered at different current levels and a quench was provoked. Following that, the magnet was taken to nominal current. This magnet, which was suspected to require training quenches, reached nominal current after two quenches (3910A and 4224 A) before reaching nominal current (4310A) [see the HC Twiki pages for details].

Commissioning now proceeds with Q4 and then D2 as well as the associated orbit correctors the same region.

In the meantime, the cryo team has continued with the tuning of the pumping group and the 4.5K refrigerator and has started cooling down the arc down to 1.9K. This morning (Thursday, May 24) half of the arc was below lambda point. The Power Converter, Interlock, Current Lead, Electrical Quality Assurance and Quench Protection System teams have started the preparation for the powering of the arc early next week.

Powering Tests of Sector 7-8: activity of Wednesday 23/05.

Today the activity was concentrated on Q5, which was released by MPP after analysis of the quench of Monday morning.

The following tests have been executed on Q5 (MANUAL execution):

ramp to nominal (4310 A) with 5 A/s ramp rate: quenched occurred at 4210 A on B2 aperture; preliminary analysis confirmed it was a training quench;
ramp to nominal (4310 A) with 5 A/s ramp rate: NO quench; a plateau of 10 min was mantained for possible voltage drift recording;
keeping B1 power converter at nominal current, B2 power converter was lowered to 55% of the nominal current (2370 A); with this unbalanced configuration, a quench was driven by QPS generating an artificial quench signal from one current lead detector; test was successful;
ramp to nominal (4310 A) with 5 A/s ramp rate: NO quench; a FPA was provoked from power converter, with an apparently too high ramp rate which triggered the quench detector.

Proposal for the activity of tomorrow.

Q4 and D2 will be tested from CCC.

Works towards powering the main circuits in the arc and the 600 A correctors (before reaching 1.9 K):

plastic bags on 600 A leads (action S. Kockorowski);
IST of QPS for which 1.9 K is not required (action R. Denz);

Once 1.9 K are reached:

ElQA for the three 13 kA circuits and some selected 600 A correctors (list to be provided by HCC; action D. Bozzini);
IST of QPS at 1.9 K (action R. Denz);
OK from PIC, PC, EE and Current Leads.

Powering Tests in Sector 7-8: activity of Tuesday 22/05.

The Powering to Nominal procedure was started fro the following circuits:

	PNO.1	PNO.2
RCBCH5.L8B1	O	O
RCBCv5.L8B1	O	O
RCBYH4.L8B2	O	O
RCBYHS4.L8B1	O	O

Several problems were faced:

cryogenics instabilities which delayed the CRYO START signal:
- oscillating level on DFBMC
- high temperature on the first 6 kA in DFBMA (54 K)
delay for PNO.2 step for RCBYH4.L8B2, whose origin was:
- hardware limitation of the PC, which blocked the cycle to 52 A; the PC went on fault and the current drop to zero (intervention of PO to remove the limitation)
- probably due to the problem just mentioned, a very long PM file was produced which was preventing the cycle from being restarted (manual reset of the PC was needed)
RCBYHS4.L8B2 showed a possible NON-CONFORMITY: while preparing this circuit for PNO.1, a high voltage value was detected on a lead (250 mV); a verification of PO showed that this is probably due to an open voltage tap. The circuit has been removed from the SOC.

PROPOSAL FOR WEDNESDAY 23/05:

continuation of tests on RCBCH5.L8B1, RCBCv5.L8B1, RCBYH4.L8B2 and RCBYHS4.L8B1;
Powering to Nominal procedure for circuits RCBYV4.L8B1, RCBYVS4.L8B1 and RCBYVS4.L8B2;
continuation of tests on Q4 and Q5 if released by MPP;
continuation of tests on D2.

Powering tests of Sector 7-8: activity of Monday, 21

Morning activity. The following tests have been performed on Q5 (MANUAL execution):

verification of p-p voltage vs ramp rate (problems with high ramp rates had been discovered last week): ramping up to 200A with 5 A/s, to 400A 7 A/s and 600A with 9 A/s;
HCA PLI3.1a: ramp to 2500 A with 5 A/s ramp rate;
HCA PLI3.1b, unbalanced cycle: starting from 120 A, one converter ramped to 2500 A at 5 A/s, the other ramped to 1375 at 2.5 A/s;
HCA PLI3.1c: skipped after agreement between experts from the different systems;
HCA PLI3.4: no icing confirmed by Amalia;
HCA PNO.5: ramp to nominal (4310 A); during the ramp, and at the current value of 3941 A, a quench occurred (analysis on going).

Afternoon activity. The following tests have been performed on Q4 (SEQUENCER execution):

HCA PLI1.1:
- first test aborted because the FGC server didn't autorized lhcop to access the power supplies (intervention of S.Page);
- test stopped, this time because of a cmw time out exception;
- test failed again because the software current limit have not been set correctly in the FGC;
- test OK;
HCA PLI1.4: FPA at 250 A;
HCA PLI1.7: ice absence verified;
HCA PLI2.1: current to interm1 (600 A); current reached without problems, but during ramping down the sequencer blocked because of an attemp to reduce the needed time to stand-by
HCA PLI2.1: repeated, but during the ramp, around 300 A, a quench occurred (investigations on going).

Proposal for tomorrow:

MPP will analyse the data collected on Q4 and Q5, with the feedback from QPS experts;
the test activity will focus on 120 A correctors.

Powering Tests - 1000A in Q5 -

Done on Friday 18.05.2007

9:30	Powering Procedure for RQ5B1(B2).L8 started
11:30	PLI1.1-4-7 I_inj: 350A PLI2.1-3-4 I_int_1: 1000A procedures performed manually and NOT using the sequencer
13:00	Boil-off test on DFBMA-C

Remarks on the work of the last week (14-18 May)

The current was ramped to 1000 A, and the magnet was quenched by triggering the firing of the quench heaters.
The different teams performed a preliminary analysis of the data that had been taken, and some observations were reported:
The DECOUPLING BETWEEN THE TWO CONVERTERS WAS EXCELLENT. By applying a modulation on one power converter of 10A at a DC current of 1000A it was measured that the coupling is negligible (ppm level). The modulation was seen by the quench detectors, but was below the threshold. For future tests, it was suggested to include the current modulation into the procedures, if required (Action: D.Nisbet).
The balancing of the QUENCH DETECTORS was very good. The THRESHOLD was set to 20mV, and the detectors did not trigger. However, it was noted that the PEAK AMPLITUDE OF THE BALANCED SIGNAL WAS SLIGHTLY ABOVE 20mV, BUT FOR A TIME LESS THAN THE VALIDATION TIME OF THE QUENCH DETECTORS OF 10ms. This effect depends on the speed of the ramp, and decreased between the first ramp at 13A/s AND THE SECOND RAMP AT 10A/s.
FOR THE FUTURE COMMISSIONING OF Q5 A RAMP OF 5A/S WILL BE APPLIED, in order to reduce the noise level for the quench detectors. The modified value should be integrated into the sequence. In the second phase the sensitivity of the quench detectors as a function of ramp speed will be further investigated. It might be required to increase the quench detector threshold from 20mV to a higher value. The objective is to ramp the magnet with the nominal rate of about 10A/s.
At the first glance it appears that all required data after the quench were recorded and written into the PM system.
The heater discharge worked as expected. It was correctly recorded, but due to one point with the wrong time the start of graph was wrong. This will be corrected (Action: R.Denz and A.Rijllart).
THE DATA FROM THE CURRENT LEADS (VOLTAGE ETC.) LOOKED OK. It was noticed that the voltage was high during the trigger of the heaters. This is due to the fact that the quench heaters are triggered using a test signal, and that the effect does not indicate an increased voltage across the leads.
AFTER TRIGGERING THE QUENCH, THE HELIUM LEVEL IN THE Q5 MAGNET CRYOSTAT DECREASED IN A SHORT TIME (~MIN) TO ZERO, and increased in about the same time to the nominal value. No change of temperature and pressure were observed. The valve opened after the quench. Since similar changes of the helium level were recorded at other occasions without quenching magnets, it is questions if this effect is real. This needs follow-up, since such drop of helium level would trigger a power abort (Action: ACR). OTHERWISE NO CONSEQUENCES OF THE QUENCH WERE OBSEREVED IN THE CRYOGENIC SYSTEM.
Since the procedures were executed without the sequencer, that data that was recorded needs to be put into MTF manually (Action: HCC)

Program for Monday 21.05.2007

Continue commissioning of Q5, manually without the sequencer.
Start commissioning of the 120A circuits using the sequencer. This can be done in parallel to Q5 commissioning, although there might be some interference.
When Q5 is commissioned, Q4 and D2 will follow. Before starting to commission D2,y the QPS team needs to intervene in order to correct a problem that was reported after PIC2.

Powering test - Sector 78 - Tuesday 15th

Done on Tuesday 15.05.2007

9:30	Test start on D2 – QH on.
9:40	Up to ~90A apparently without QPS protection – Actually It was not the case.
15.24	QH enabled for RD2.L8, QPS interlock problem on D2 understood. Only the displayed ref. voltage was a sum of the voltage picked up from the two apertures instead of a difference. At the level of protection the signal was right.
15:34	PCC start on D2 - up to 200A at 16:00
17:30	Loss of Cryo-Start and Cryo-Maintain due to a hardware intervention. Physical cryo conditions were stable. Signals recovered after few minutes.
16:23	PCC for D2 finished successfully
17:40	HQ of RQ4.L8 on – Reiner changed
17:50	Still problems on Q4 – Picked voltage exceed 20mV when PC tries to start up – QPS trips the PC.

19:00	Tests end

Cooldown Sector 78

Despite the long series of faults (network, cooling water, pumping group) experienced at the end of last week, the cryo team managed to bring down the average temperature of the magnets to 3 K during the week-end. The switch over to the new cryoplant took place on Monday but the connection of the new pumping group was delayed until Wednesday morning. Stabilization of temperatures and pressures as well as fine adjustments of the plants took place most of Wednesday until Thursday at 11.30 when the pumping group was set at 15 mbar. Unfortunately, at 11.30 an attempt to restart the UPS system on the surface caused a power cut which stopped all the PLCs. The cryo team is still recovering from that failure and we expect to be at nominal cryogenic condition in the arc tonight Friday May 4th.

Following a top management meeting which took place on Monday, a series of measures towards the clearing of the difficulties with the commissioning of the DFBs were taken: two different ways to avoid condensation on the chimneys are now in place: blowers on 6kA leads + heaters on the 120A leads on the DFBMC and dry-air bags around the chimneys of the DFBMA.

Although the powering front was very quiet during the week, significant progress was achieved with the preparation of the sequencer for the independently powered quadrupoles and the 120A correctors: we now have the sequencer tuned for the 60 A and 120 A correctors as well as the independently powered quadrupoles and D2.

Status of LSS8

The final Access system is being installed in P8. We could see the personnel and material SAS in the UA (Angels and Demons' eye recognition !!). The bake-out of the kickers in LSS8R is taking place, and should be at nominal temperature by wednesday ! The TDI is still not in place, though. We show here also the new vacuum valves.

Long Straight Section in P8

Friday 13th October I visited the Long Straight Section in P8 up to the TI8 injection line. Here I post some photos of the status of the installation and particularly about the bake-out preparation of the MKIs. You can see how TI8 enters at the MSI level (beautiful !!). Details about collimators, and BLM are also shown. The TDI was not down yet !

..au-dessus de la QRL ,les boites a cables etaient venues .. se reposer tout contre les vannes cryogeniques qu 'on apercoit sur la photo. Fort heureusement aucun degat n 'est a deplorer et tout est rentre dans l 'ordre apres que Jean-Claude Guillaune ait fait corriger le probleme en faisant raccourcir les corgages nylon qui soutiennent l 'ensemble cables en court-circuit et boites isolantes , cordages maintenant cet ensemble a bonne distance des fragiles vannes en question qui peuvent desormais vaquer a leurs occupations de vannes... Tout va etre mis en oeuvre pour que ce probleme ne se renouvelle pas.

tests HT des cables refoidis en UA43: OK

Les problèmes de fuites ayant été resolus par CV qui a travaillé "ferme" ce week-end,les tests HT des cables de puissance(avec eau de refroidissement) ont pu se dérouler comme prévu ce soir 10 avril( avec bien sur la bonne qualité de l 'eau en ce qui concerne sa résistivité). CV a signalé également que l'équilibrage sera revu quand les branchements "eau" sur les convertisseurs de type RYM seront réalisés. Les mesures d 'isolement s 'étalent de 20 (environ) à 100 Mohm dans le meilleur des cas pour les cables refoidis. Un élément important à corriger (photo): un court-circuit avec la masse sur les piquages desservant RA / RB a été mis en évidence pendant ces tests: raccord eau touchant le caisson de protection métallique des tubes cuivre de puissance. Une solution Mac Gyver TRES(!)provisoire a été trouvée (ligature fibre de verre d'emballage...) pour vérifier que ce court-circuit était bien le seul sur cette ligne ....

Une photo montre le foisonnement des câbles sortant des RYM et également que les dessus des racks n 'ont pour l' instant pas reçu leurs doses de copeaux métalliques comme ce fut le cas en UA 47, on croise les doigts....

...Et demain est un autre jour....

Acqua Alta en UA87

Des problèmes de serrage, de joints plats et donc d étanchéite sur les connections de sortie des convertisseurs RQ7....RQ10 en UA87 ont tenté de plonger momentanément l 'UA87 dans une période de hautes eaux.... (photo) ce vendredi 7 avril, alors qu' on mettait la dernière main à la réalisation des connections de puissance sur DQRB.......

Cependant que Noel (Fournier) et des techniciens, à l'abri dans l'enceinte insonorisée de DQSB poursuivaient leur travaux, et continuaient de poser les sondes de températures et voltmètriques pour les connections de puissance (photo)...

Mais les tests HT sur les cables - initialement prevus lundi soir- vont peut-ètre devoir ètre reportés au mardi soir,.et le personnel CV devra s'affairer ce week-end afin que toutes les raccords "eau" soient parfaits...

LSS7R short-circuit tests soon

Dear all, Once UA87 will be completed, we are immediately supposed to start the short circuit tests in RR77. In less than two months. A status of the installation works in LSS7R seems adequate at this stage. Proposal: next HCC meeting, April 20 15h30 in bld. 30.

letter from Jean-Pierre Malod-Dognin

Comme je suis allé faire un’’ tour de chauffe’’ dans la RR77 ce PM, je me permet de vous faire profiter de ces quelques photos (une fois n est pas

coutume) que j ai cru bon de faire, comme une carte postale du bout du monde (faut pas pousser quand même… )

Les choses sont moins ‘’étendues’’ que je ne le pensais a priori.. .

J ai matérialise les emplacements des convertisseurs par des flèches rouges (c est leurs seule position possible, je présume..)

Les ‘’ contacteurs ‘’ sont au premier étage et accessibles seulement par une …échelle (flèche verte)

Essais en court-circuits UJ56 et RR57

Bonjour,

Les visites des installations électriques des ouvrages cités en objet ont été réalisées à ce jour. Aucune non conformité ne s'oppose à ce que les essais en court-circuit soient effectués à partir du 20 novembre 2006. Les rapports de visite parviendront ultérieurement aux responsables de chaque installation.

DC connection sur 5kA Inner Triplet à USC55

Allo Roberto!

Le systeme de detection de defaut de terre interne au convertisseur a encore passe avec succes le TEST DE CONTROLE...

Bonne soiree Hugues

PS: JC Guillaume est en train de traiter le pb.

Bonjour,

Suite à un défaut "Earth Fault" affiché sur le convertisseur 5kA Inner Triplet HCRPHGC__-KP000003, nous avons investigué le problème. Il s'est avéré être un court-circuit franc entre le DC Output du convertisseur et le GND (Il n'y avait pas la tension Vearth en mode actif et un test à l'ohmmètre a indiqué 0ohm entre le DC- et le GND). Après un rapide coup d'oeil, nous nous sommes aperçu que les vis permettant de raccorder le câble à eau sur DC-, touchaient le capot de protection des diodes de roue-libre (voir photos jointes). Le nécessaire a été fait pour contacter les personnes responsables de ces connections et les modifications seront faites dès demain.

Bonne soirée

Amitiés

Vincent

eau gl. 4-5

And here it is the demin. water plot.

The power is very low (mean power around 200 kW), which is creating some pumping of the regulation (the reg. valve is opening and closing) as the nominal power of the circuit is 1400 kW. We are going to slow the PI to see if we get a smoother plot.

Please find below the plot for RR53, today at 13:21 hours. The system is working according to spec. (high speed since about 10:00 h). Keep in mind that the nominal values requested by specification are: Temp (mean) ground floor: 28 (+- 5) C Temp. (mean) top floor: 30 (+- 5) C

The measured values are (at 14:04 h) Temp. (mean) GF: 24.2 C Temp (mean) top : 30 C (vault) Temp mean regulation: 27.1 C

Water monitoring in UW45 is also underway and according to spec. Plot in the coming minutes.

We are at this moment discussing with J.C. Guillaume (on site) some adjustmemts to try and improve the temperature of his cables.

Diagnosis of MB.A45 circuit shorted to ground - Courtesy of D.Bozzini & J.P.Tock

This morning MCS has open the diode box of the dipole 3186. AT/MEL has connected an ohmmeter during the operation to follow the status of the short. At the time of opening the big flange of the diode box the resistance to ground started to change (increase). After the opening it could be possible to first see a quite big quantity of dust on the diode metallic box and second some big pieces of welding residuals.

After having disconnected the diode at the level of the half moons the short disappeared (infinite resistance) and in at the same time some debris felled down from the top part of the half moons. As you can see in the attached pictures the size of one of this residual fits perfectly between the live part and the metallic body of the bus bar duct. In addition in one picture you will see a carbon trace on the G10 insulating piece. This could be provoked by the current of 1A we injected to better localize the fault position flowing through the debris supported onto the G10 piece.

The system will be set back to the requested pressure condition (6 bars in the magnets, 2.2 bars in the DFBA's - which should be achieved by Tuesday 3rd July), when the ELQA-TP4B qualification of this faulty circuit will be repeated.

Beam Instrumentation - BSRT Installed and Aligned

The two BSRT telescopes were Installed last Monday in LSS4.

LSS4L: The BSRTD has been connected to the BSRTM and the system successfully aligned with the laser.

LSS4R: The vacuum chamber in IP4 right side is still intact after the BGI bake-out incident and therefore connection and alignment of the BSRT right side will be done tomorrow !

des tests HTdes cables refroidis de UA43

Les tests d isolement des cables refroidis de l UA43 ne s averent pas tous positifs... Apres bien des interrogations , il semble que l eau contenue dans les cables soit de tres mauvaise qualite et perturbe considerablement les mesures ... Apres discutions avec Loic Bougeois, il ne semble pas d actualite de vidanger ces cables refoidis mais plutot de faire circuler l eau demineralisee en vue de la debarrasser des impuretes qu elle contient... Travail effectue apres la pose des eletas...et le raccordement aux switchs.

Field Control Room in UA43

At the request of Sebastien Pelletier from TS-MEL/Cabling Section, I asked Pierre Charrue and his team to remove all the computing equipment in UA43. The PCs, monitors and the big screen are now stored by AB-CO. A request to re-install this must be made to them a month in advance of the start of the Short Circuit Tests in UA43 en of July 2006.

SCT in UJ33

https://twiki.cern.ch/twiki/pub/HCC/BlogEntryPoint3x2007x05x04x18x27/GlobalAnalysis24hHR_UJ33.ppt

During the 24hr heat run major problems were found (for a more detailed description see the attached file):

1 - Over-heating of the systems in UJ33 (central part) – TS-EL will re-routing the cables inside the UJ33.

2 - Over- heating of the cables in the tunnel side RZ33 – a vertical cable tray will be positioned parallel to the TS-CV cooling water supports. The tray will host one of the three cable layers that are now placed on the same tray.

The re-routing cable works will last approximately up to the third week of June. The integration/cost studies are on going and the possible co-activities interfering with the preparation for the cooldown of the A34 are being taken into account.

A meeting to up-date the "status of the art" is foreseen for Monday 14th. Details will be given.

During the inspection of the UJ33 P. Proudlock commented:

1 - ODH system must be foreseen in UJ33 - the DFBLC inside the UJ makes it indispensable

2 - Rectangular ducts (for the geometers) must be closed during the heat-run

Comments: HEAT RUN CANCELLED

Maintenance of the water-cooling circuits coming form Point 2 providing water also to the cooling circuits of the power converters in UJ33 was planned to be performed between 02.04 (today) and the 20.04. This manipulation was not taken into account during the planning of the SCT in UJ33.

The maintenance caused the stop of the tests and was irreversible: it will be not possible recuperate the cooling power until the end of the intervention.

The tests has been rescheduled in agreement with TS-CV. The priority will be given to the work in SX2 (the primary circuit) in order that the water in UJ33 will be available the 16.04.
