COMMENT ON PSS Runtime Miscallenous Repairs

1 day 16 hours ago
Log Number: 4488559Logbook(s): Body: 

For the upcoming maintenance period SSG will have some tasks we would like to perform while the machine is open. Most of these tasks are non-invasive ( no recertification needed etc..) and opportunistic tasks, so we would work around or postpone the tasks based on other higher priority work in the area if needed.
The tasks are;
North Linac - (1) MPS documentation checks mainly in the east arc region of NL (1 hr +/-)
(2) BLM predicted vs.

Arc A Vacuum Burp

Looks real. We aren't sending beam here though.

Seems to happen occasionally (see figure 2 and attached elog). It's not an issue now but may be when we are setting up beam to Hall D. VIPAA05 Looks to be the most affected.

Apologies if there is already an Ops-PR about this. I couldn't find one.

As always, ensure the PTW is on-issue before proceeding. RAM Movement request will need to be coordinated with RadCon for removing the in-place PTW.
