Following the vacuum issue this morning, the vacuum gauges for BSC2, BSC3 and HAM6 have been added back to VACSTAT. These gauges, plus HAM1, had been removed from VACSTAT at the beginning of the vent on 02apr2025. A temporary IOC vacstat_dummy_ioc.py had been running to serve the missing channels to the EDC.

This evening I added BSC2, BSC3, HAM6 back to vacstat's prod.yaml and restarted the service. I then removed these from vacstat_dummy_ioc.py (it now only simulates HAM1).

I re-enabled the VACSTAT multiple gauge alarm to the vacuum team in the alarms system, which was restarted at 18:34.

After the vacstat restart we quickly got a delta-p alarm for BSC2 because it still had the default sensitivity of 1e-08 but the vertex is currently running in the 1e-07Torr range. The sensitivities for BSC2,3 and HAM6 were reduced to deltap=1e-07 and vacstat was restarted.
