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

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
