GangPhase slippage throughout Day Shift
[11:51] Begin an ongoing ELog and track GangPhase slippage throughout the Day shift...
FIG.1 - 1A & 2A ~noon
FIG.2 - 1A & 2A ~15:40:00
GP in the north had been slipping more than ever, seems like every 20 to 40 min it strays.
FIG.3 - 1A & 2A ~15:56:00
Even now it's slipped even more after only 10min
Hall D is experiencing oscillations in bpu positions
Hall D had mentioned some unfavored oscillations in bpu (and 5C11B?) positions
Looking at the PID lock for bpu x & y, there is no P-gain or D-gain.
I-gain is set to -100 for X and +100 for Y
I think we should back off the I-gain and add to the P-gain. If we change the PID's a little at a time, look at the effects on position, and make more adjustments or conclude our adjustments as nominal
I'm going to consult with my colleagues beforehand, but the first set of changes would probably look something like this:
(X)
P = 20
I = -80
D= 0
(Y)
P = 20
I = 80
D= 0
