LVPS Trip monitoring in 2022
From Stan:
LBA33 and EBC58. Both have troubles to start MB_side bricks - see https://pcata007.cern.ch/elog/Maintenance/4980
- In LBA33 we saw HV and DIG bricks started but not MB bricks.
- In EBC58 all but Dig+5 bricks started.
The ATLAS detector is already closed - we have no possibility To replace LVPS until next shut down ( dec 2022)
