Unbypassing zone with state bit only vice script with tuning just to get zone into filaments and HV. Informed Crew Chief at 1220 of my intent and that I wasn't going to use the script or retune any cavities, just get it into HV for warm up soak. 3/10 a 12v fuse replaced in cavity 5 RFCM supply distribution chassis and a RFCM staged at the zone just in case it blows again when we put it back into RF next week. Already blew this Wednesday since it was replaced 01/25. Found KFVM at 0.0 v when bringing zone into filaments so cavity 8 will need looking at filament readbacks next week.

Running in RF until end of Moarch 2026 with .8 KMAV with KCCU at 1.32 a . Just tried turning zone into HV and tube was dropping on high KMAI until I put the full 2 kv of KMAV on it. KCCU at slightly over 1.0 a and KMAI at a steady .634 ma. Will let the tube run like this over the weekend to let the tube soak in HV and see if we can fully recover it on Monday.

Been adjusting quads in the 2C22, 23, 24 triplet. We've been having some small success with this but nothing substantial.

As of now, we've paused beam to Halls C and D so we can insert the Hall B viewers to see if we can make some headway by adjusting the quads and watching how they affect the beam spot.

After reducing halo rates to an acceptable level, Hall B started taking harp scans at 2C21 and the tagger. 2C21 looked about the same as it did on Wednesday but the tagger scan showed a very wide profile in the x-direction which also has a sharp edge.
We are attempting to adjust the triplet quads MQK2C22, MQR2C23, and MQK2C24 to tighten up the x-direction. So far it seems weakening MQR2C23 is having the best results.
