Pre-vent checklists
- Turn OFF PZT high voltage
- Close shutter of PSL-IR and green shutters at the ends
- Make shure the jam nuts are protechting bellows
Reduce input power by placing wave plate setup BEFORE THE PMC.
Alignment procedure
- Align MC (center beams on MC mirrors (MCAss))
- Put input PZTs in center of range.
- Place cage-mount aperture targets on BS and PRM cages
- Using PZT mirrors ONLY, center beam in PRM aperture, and on PR2 folding mirror, and center PRM retro-reflection in YAW at PZT1/Faraday.
- Adjust PRM pitch biases to center retro-reflection in pitch.
- Add brass-mount apertures to ITMY and ETMY.
- Unclamping and adjusting in yaw, adjust PR2 and PR3 folding mirrors such that beam is through BS, ITMY, and ETMY apertures.
- Using PR2/3 pitch hysteresis, adjust pitch to center beam through BS/ITMY/ETMY apertures.
- Adjust ITMY biases to center ITMY retro-reflection on BS.
- Put apertures on ITMX and ETMX cages.
- Using BS, center beam on ITMX/ETMX. NOTE: SHOULD NOT BE TOUCHING INPUT POINTING/PZTs.
- Adjust ITMX biases to center ITMX retro-relfection on BS.
- Should be able to see AS MICH flashes.
- Adjust SR2, SR3 to center beams on SR3, SRM.
- Adjust SRM for retro-reflection of AS beam at BS.
Closeup checklist
- Center beam on all AS optics
GET CAMERA IMAGES OF EVERYTHING
- We must get images right before closing, right after closing, etc.
- 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
Close PSL shutter & green shutters at the ends
- Check jam nuts
