Hall B Optics Tuning
Hall B's beam is too large on the 2H00A Harp (see linked ELog). I made a small adjustment to MQK2C22, MQR2C23, and MQK2C24 (see fig 1), to try and squish it down.
Upon sending back, the halo rates look worse so it is possible that this was the wrong direction. Hall B is scanning their harps now.
Profile looks tighter but they are still seeing a vertical tail.
I made a larger adjustment to MQR2C23. The guidance indicates the middle quad is the one to use when only one plane needs to be adjusted. Halo rates seem unaffected.
Hall B is doing a harp swipe now.

Crew Chief Shift Log, 2026-05-09 DAY
Start of shift: Beam to HB/HC
Cannot save Beam Time Manager timesheet at 15:00
Yesterday I was not able to save the BTM after 15:00 as required by the Crew Chief. However, I was able to submit it a few min after 16:00.
Today I had the same problem at 15:00. See attached screenshot.
Both yesterday and today I spoke with the Crew Chief and he made a note of this.
