10:25: Lockloss
1) ALS Polarization (see attachment)
Since we were down decided to adjust ALSx polarization (was at 31). Only managed to get to 27. Doing this sent ALSy to la la land, so instead of 1 it shot up over 100. So I reduced it. Only made it to 4. Proceeded with locking.
2) Locking Operator Play By Play
Getting hang of new procedure. Which includes seeing ALS_[X/Y]ARM with the UNLOCKED state selected.
- First thing observed was ALSy was not looking good. It was locked on a bad mode and we were stuck.
- Operator Manual Adjustments: So I brought out ALS_YARM "all" screen & selected UNLOCKED and touched up via ETMy & TMSy
- Operator Manual Adjustments: Then I selected OFFLOAD_ETM_TMS_WFS (this is new from what I'm used to).
- Operator Manual Adjustments: Then continued on as normal. Decided to go for PRMI from previous experience and touch up alignment (POP18 only up to about 55).
- 10:47 - 10:52 Time for DRMI to lock (after it locked, I did NOT pause here, I just selected NLN & let ISC_LOCK do what it was going to do.)
- 11:00 ASC goes crazy at ENGAGE_ASC_FOR_FULL_IFO with lots of Verbals.
- 11:01 Makes it to ENGAGE_SOFT_LOOPS (Verbal pipes down).
- 11:17 NLN
Have significant figure diffs for FSS & SR3 again as noted for previous lock. ACCEPTED these again.
