- 10:30am, re-aligned optical system to horizontal reference
- 10:37am, in chamber balanced
- 10:38am, started roughing pump
- 10:52am, started turbo pump, pressure was <2 Torr
- disk got briefly excited when the pump was at ~60 Hz, and again at ~200 Hz,
- centered QPD with picomotors at 10:54am,49
- pump at 500 Hz at 10:55am, no more disk excitations.
- IGM on at 10:55am, disk moved briefly afterwards, not sure if correlated since the IGM controlled is still showing "STARTING".
- Disk definitely moved at 10:57:40, when the IGM controller started showing pressure.
IGM switched off at 10:58:45am, disk is not going back!
- QPD recentered using picomotors.
- IGM on again at 11:00am, no disk displacement this time.
- 12:20pm:
- quiet time before excitation 1162585209
- excitation
- quiet time after excitation 1162585348
- 1:49pm: excitation again, 2kV, quiet time after 1162585348
- In both the previous excitations the QPD got misaligned at the beginning, resulting in not very good ring-downs
- Another trial at 1162597014, amplitud 1.5kV. Somebody switched on the light in the lab...
- pumps stopped at 4:09pm
