SHIFT SUMMARY: Strugggled to align the IFO this shift but now been locked for 1h45.
LOG:
- 16:00 When I arrived Jim was stuck in INITIAL ALIGNMENT at LOCKING_GREEN_ARMS with no light on ALS_YARM. We exited out of Initial by taking ISC_LOCK to DOWN, INIT.
- 18:00 My fob wouldn't let me in this morning and access system seemed strange so after talking with Richard, Carlos came in to restart the server. My fob had expired and he updated the assess system.
- 18:26 started Initial Alignment as couldnt lock PRMI
- 19:26 Pushed INIT, DOWN on ISC_LOCK as we've spend 20 minutes stuck in ACQUIRE_MICH_BRIGHT and then 20 minutes in ACQUIRE_SRY.
- 20: 21 Started Initial Alignment again as couldn't lock PRMI and kept loosing lock when moving BS
- 20:30-20:50 Daniel on site.
- 20:41 During INITIAL ALIGNMENT, FFS was oscillating, so following Jason's instructions in (alog 54445) I toggled FFS power on a 00 mode and that locked. I then took laser power to 2W to get IMC locked. Keita, by phone, helped me though initial alignment as we couldn't get MICH_BRIGHT to lock, see (alog 54584)
