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
- RQ5.L8:
- Squeezing Tests: Done after the meeting - Test OK
- ElQA:
- Scope installed and system callibrated using artificial 100 mV spikes.
- The measurements on the lead heaters insulation gave correct results.
- Reiner will provide a way to measure the insulation between the quench heaters and the coils.
Planning for Monday 11/06/2007
- RD2.L8, RQ4.L8. RQ5.L8:
- Special test explained on Wednesday will be applied as soon as AT/MEL has completed new instrumentation in the RD2.L8 circuit.
- 600A Correctors in the DFBAO:
- Reiner will try to release some circuits for PCS tests on Tuesday. Circuits released by ElQA and connected to the leads are:
- ElQA:
- Tests will continue in MBA line.
