Powering test in sector 78 - 30-31 May 2007
| |
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 |
|
| |
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 | |
| |
Provoked unbalanced quench with (B1 at nominal). Ramp down from nominal this time worked OK. PNO.8c OK. |
| |
RCBYVS4.L8B1; RCBYVS4.L8B2; RCBYV4.L8B1; RCBCH5.L8B1; RCBCV5.L8B2; RCBYH4.L8B2; RCBYHS4.L8B1; should go through PNO.3 and PNO.4 |
| |
Current cycle up to nominal PNO.9 on Q5. |
| As soon as they are released, the squeeze function test will be performed on these 2 circuits. |

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 .

Powering Tests in Sector 7-8: activity of Friday 25/05.
The day was fully devoted to perform tests on D2.
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.
- ElQA on the selected circuits: see presentation of Davide in the last post.
- Quench heaters qualification, without interference with ElQA.

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);
- 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 |
- 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.
- 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).
- 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).
- 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.

| |
| 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). |
| |
| |
| Since the procedures were executed without the sequencer, that data that was recorded needs to be put into MTF manually (Action: HCC) |
| Continue commissioning of |
| 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.
