Cavity 7 RFCM full output measured -6dbm which is good. 2.5w and drive cables need checked. We are out of 2.5W amp spares so this cavity will have to wait. Cavity 6 RF was recovered to 12.0 Mv/m after downloads corrected from RFCM installed 01/21/26 and RF not checked until 02/11. Cavity 8 has good drive but tuner is way off after tuner repairs by SRF. Tuner slipping problem started 06/24/2025 and Mike M. did some tuner movement checks downstairs on 02/11/26 and it was moving freely. Need to make sure Camac stepper card is working with a tune cart to find out if it is moving by EPICS.

Due to harp IHA3H07B needing to be removed/repaired, beamline vacuum between VBV3H04 and VBV3H07 valves will need to be bleed-up. VBV3H07 valve cable is still connected to valve simulator box, so epics readback for this valve is to be ignored. Big possibility that the valve leaks through to the target and will need to be replaced. Vac group will decide this during harp removal work.

IHA3H07B is damaged, Beamline between VBV3H04 and VBV3H07 will need bleed-up when I&C is ready to remove for repair; VBV3H07B possibly has leak-through gate if it does; we will also change-out with new same type VAT F-01 valve.

1C05 dumplette on BSY_2 FSD node is showing as faulted and it is unclear why that is the case. As can be seen in Fig. 2 and Fig. 3, the dumplette is able to be inserted and retracted without issue, but fault will not clear in the FSD node.

The early 1C valves are causing an FSD fault for Node BSY_3 when masked to the BSY. These valves have associated ABIL entries for them as the Hall A beamline is being re-worked for MOLLER. All valves on this FSD bit are only 1C so it is safe to mask. Received verbal permission from the Acting Director of Accelerator Operations to mask this FSD bit and submit an ABIL entry.
