At my arrival, ITF was completed lock acquisition and ENV activity still in progress.
- Valerio coming back from central building at 14:15 UTC (see subsystem report)
- ENV activity concluded at 14:55 UTC
- 14:55 UTC SQZ commissioning activity planned started and proceeding with no problems until 21:00 UTC
- 21:01 UTC Science mode
ITF left in Science Mode
Guard Tours:
- 18:50 / 19:30 UTC
- 20:45 / 21:17 UTC
Software:
- 16:21 UTC stopped and restarted Telescreen Right VPM process
Sub-system reports
DET
18:31 UTC B5_QD1 galvo loop closed manually during the lock acquisition
SUSP
Trying to solve the issue about unlocks caused by drifting of PR accelerometer signals, V. Boschi done a reset of the board.
If the problem persist (see entry #63696 for signals to watch for), disable the inertial damping
During the shift, experts saw an higher oscillation on BS Top Stage.
After some checks, it seemed to be related to noise injections performed previously. Problem solved itself by opening and closing inertial damping
Calibration
(22-03-2024 21:00 - ) Start with weekly calibration scheduled at 23:00 UTC
This is a request from M. Vardaro because at the end of his activity, he turned off some devices under the bench.
This may take a couple of hours for temperature adjusting, so he would like to take data with ITF locked during this transient.
Signals that could be drifting are under SQZ_INJ flag (SQZ_MIRROR1_X and Y, SQZ_MIRROR2_X and Y)
