Powering test in sector 78 - 30-31 May 2007

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.

PROPOSAL OF THE ACTIVITY OF THURSDAY 31/05/07

CORRECTOR CIRCUITS (Q4,Q5) RCBYVS4.L8B1; RCBYVS4.L8B2; RCBYV4.L8B1; RCBCH5.L8B1; RCBCV5.L8B2; RCBYH4.L8B2; RCBYHS4.L8B1; should go through PNO.3 and PNO.4
RQ4.L8
RQ5.L8
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.
