- 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
