Powering test in sector 7-8. 31 May - 01 June 2007

COMPLETED ON 31/05/07

Q5 Complete cycle of Q5 up to nominal current (4310 A) PNO.8d. Test OK.
Correctors of Q4 and Q5
Battery test of six correctors: PNO.3. Test OK.
Battery test of six correctors: PNO.4 (SPA). Not OK for FGC software problem.
Q4 corrector released by MPP after quench analysis. PNO.3. Test OK.
D2, Q4, Q5 Powering to nominal cycle of all the matching section ML8 together. Test not OK for quench in D2 and Q4. The quench occurred when all the circuits were at about 80% of the nominal current. Maximum was 5268 A for D2.
ElQA 13kA Completed for RQF and RQD.
In RB discharged at 1.7 kV (1.9 kV nominal). Cryo instrumentation was disconnected and next discharged was at 300 V. In the evening it was foreseen to repeat it with all the electronic disconnected.

PLAN FOR 01/06/07

ElQA HV tests dipole circuit
RQ6.R7 High voltage test to be repeated
RQ6.R7 in DFBMH Once ElQA finished and insulation plug restored
* QPS controller to be reprogrammed
* Current leads to be connected
* PCC Circuit Config
Matching Section ML8 Blocked by MPP till deeper understanding of the quench event. No powering tests till MPP releases it.
