STATE of H1: Commissioning
INCOMING OPERATOR: None
SHIFT SUMMARY:
15:00UTC Started off the day in a Manual Initial Alignment
For the intial alignment this morning, yarm was found by hand and we had to lower the locking threshold from 0.7 to 0.5 from the ALS YARM PHD medm screen (this was reverted shortly after). To get MICH_BRIGHT to lock I had to move the BS quite a bit in Pitch (>2 microradians), for SRC locking guardian prompted me to center SR2 by hand so I misaligned SRM and adjusted SR2 to center it on AS-AS_C, which I had to move a lot in pitch again (312.2 -> 292.7).
16:30UTC After finishing IA Shiela start to work on the OMC suspension IM alignment / saturation issue
18:20 ISI HAM7 WD tripped, probably from SQZ rack workpause
Struggled to lock DRMI or PRMI even after CHECK_MICH, so we started another IA at 18:50UTC finished at 19:14UTC, Locked DRMI on the first try after this IA
Lockloss at 21:14
Struggled to get good buildups with PRMI, ASC would kill it. I tried to hold at PRMI_LOCK and touch up the BS and PRM by hand looking the slow building ups scope but I was not able to do it effectively/fast enough?
I'm starting another IA at 22:25UTC which is still ongoing as of 00:0UTC and almost finished
