Vent checklists
- Turn OFF PZT high voltage
Closeup checklist
Turn PZT high voltage ON
Put input PZTs in center of range.
- Align Y arm PLUS PR2/3:
- put alignment targets on ITMY/ETMY cages
- use alignment ruler for PR2/3
- using PZT1/2, iteratively:
- center beam on ITMY
- center beam on ETMY
- center beam on PR2/3
- use PR2/3 hysteresis to adjust pitch of PR2/3
- flashes in Y trans
- Center beam on PRM:
- height should be constrained at this point based on PR2/3 centering and Y arm alignment
- move PRM cage if misaligned in yaw
- PRM retro-reflection should come out REFL cleanly
- Center beam on BS (should not need adjusting):
- put alignment target on BS
- Align X arm:
- put alignment targets on ITMX/ETMX cages
- use BS to center beam on ETMX
- ITMX height should be constrained by BS/ETMX
- adjust ITMX cage if misaligned in YAW
- flashes in X trans
- Align SRC
- check beam centering on SR3/2/M
- adjust SRM retro-reflection for centered return beam on BS
- Center beam on all AS optics
- Make sure REFL is clear
- dither PRM, see motion on AP tables
- Make sure AS is clear
- dither BS/ITM, see motion on AP tables
- Using IPANG/POS pick-off mirrors, center beams on:
- IPPOS
- IPANG
Check all OpLevs centered, in and out of vacuum
- Turn PZT high voltage OFF
