OOC/xB APEL - Update

1 day 1 hour ago
Log Number: 4499552Logbook(s): Entry Makers: ryanmbkirstendBody: 

Initial viewer looked flat at 2C24, attempted adjusting at 2C21, didn't fix the harp scans from the hall. There were some signs of scraping, but could not see it on the viewers, despite x and y steering checks.

Adjusted the triplet at 2C23 to weaken the Y focusing and increase the X focusing. This seemed to help, though symptoms of scraping still showed up. Tried 2C22 and 2C24, but this didn't help. Backed out, adjusted 2C23 again, helped, but still didn't get rid of scraping symptoms.

Hall B APEL arrived, recommended going upstream to Lambertson.

2L10 Comm's Restored on 13 May 26 by IC

1 day 1 hour ago
Log Number: 4499539Logbook(s): Entry Makers: kernsBody: 

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.

2L03-8 Preventing HV with High KMAI Trips

1 day 2 hours ago
Log Number: 4499516Logbook(s): Entry Makers: kernsBody: 

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.
