Cleaning of the suspended test mass (Dec 2009)
Motivation
Whether contamination or not
Measurements before the vent
- Visibility measurement
- Finesse measurement
Overview of the plan
We plan for the vent from 7th Dec to 11th Dec in 2009.
Preparation
- wiping preparation
- wiping practice
- aux beam as a reference....align to overlap in vacuum
- Input PZT (strain gauge) /HV off/OMC PZT HV
- update snap shots: sus, strain gauges,IOO, OMC....etc (OMC has no strain gauges)
- recenter: IP-ANG-POS, oplevs..... at full lock
- test drive crane drives
- clean clean-tools again
- keep eyes on particle counter: abort over 10,000
- cut some viton tips for spare earthquake stop screws
Monday:
- Vent / Open ETMX if possible
- Take pictures before touching
- Record positions of the mirrors (OSEMs/OPLEVs)
~ Wednessday: - IPANG beam - ITMX position (pushing screws) - ITMX BB leveling - measure the distance of the breadboards - check of the optics in the chambers
Thursday: - Evacuation
Friday:
