From Stan:
LBA33 and EBC58. Both have troubles to start MB_side bricks - see https://pcata007.cern.ch/elog/Maintenance/4980
The ATLAS detector is already closed - we have no possibility To replace LVPS until next shut down ( dec 2022)
Current trip status is given on trip monitoring chart. All manual interventions are removed based on the table shown below.
