COMMENT ON 2026 Validation and reCalibration of the H2 Sensor for Buildings 91 and 95
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?
