18 hours 36 minutes ago
Log Number: 4466928Logbook(s): Body: 

Updated task to better capture it is for both {Hall A, Bldg91} and {Hall C, Bldg 95}. Once the PTW is on-issuewill approve. Needs to be done in Hall C prior to beam delivery in mid-March, in Hall A prior to FY27 beam delivery.

Have a date in mind for doing this task, presumably for both xA/B91 and xC/B95 on the same day?
