Turn OFF PZT high voltage

Alignment precedure

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
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
