Subject: Issue 

BKR called PRC around 06:10AM to inform on vacuum issues at SA1 beamline leading to a lost beam permission for the North Branch.

VAC-OCD found an ion pump in the PBLM / XTD9 XGM presented a spike in pressure that triggered valves in the section to close.

After reopening valves the beam permission was restored; further investigations and monitoring in coming days will continue. Currently all systems work normally.
