COMMENT ON RF work for 2026 HCO
2L25 Bay 1 and bay 4 not going to HV. Found two damaged (burned) din 120 VAC distribution blocks and no 120VAC powering Bay 4. Repair when we locate new blocks. Bay 1 has a DSP low battery fault on the battery backed RAM and lost all loaded values. Spare Display control board to go into bay 1 tomorrow after 120VAC repaired. The loss of 120 in bay 1 may also affect the memory loss in bay 1. Techs: Chris, Sam, Xavier,Gunner,Trey, Alex.

COMMENT ON Measure Real-Time Helicity Pickup from JLAB RTP HV Driver
Now, we tuned off the IA system, we have to update our plans:
1. With RTP ON and set to nominal HV, take a 4-hour parity data.
2. With RTP OFF - take a 4-hour parity data.
3. Ground PCBs to laser table and with RTP ON - take a 4-hour parity data.
4. With RTP ON, RTP electrically isolated, take 1 hour run with 0 reporting delay.
