22 hours 2 minutes ago
Log Number: 4475381Logbook(s): Body: 

With the removal of the currently installed YBBS06 magnet, the following work has been done.

ABIL tags have been installed on YBBS06 shunt chassis and ARC7 thermal interlock chassis. Jumpers have also been installed on the previously mentioned systems to enable ARC7 power supply functionality. The RTD connection cable has been removed and also jumped. The YBBS06 shunt module has been removed from the chassis. Magnet and shunt leads have been jumped in a box and tagged with an admin tag. All DC power work for magnet removal is complete.

Inherited setup #26759.
The FX settings in this setup are empirical; the previous 140 keV setup had some single-wound and some unrepaired FXs.

Moved ALH masters back to opsla0

Log Number: 4475361Logbook(s): Body: 

The RF alarms are very active today. It exposed a potential timing issue with the new RHEL9 instance running on opsla9.
I've killed the INJECTOR and ACC master alarm handlers and restarted them on opsla0.

Please let me know if you see these symptoms again.

COMMENT ON PSS Runtime Miscallenous Repairs

23 hours 11 minutes ago
Log Number: 4475358Logbook(s): Body: 

Regarding my previous comment: discussed this further with SSG group leader. My concern was that UITF PSS repairs recorded on this ATLis were not informing UITF users. To resolve this, I've created a new Enclosure selection for ATLis = UITF. I've added it to this ATLis, populated the UITF enclosure group with those from the UITFList Admin group. With this update, my concern is addressed.

Disregard my previous comment. For ATLis-s that cover the UITF, please make sure you select UITF enclosure.
