COMMENT ON Install MOLLER ADCs, VME modules and connect BCM signal cables in Injector Service Building
IPM0R05 is disconnected from test setup (Labjack) in rack IN03B23 and connected to Moller ADC. The phase monitor in rack IN02B24 was disconnected from QWeak crate previous week, so it is taken to rack IN03B25 and connected to Moller ADC.
We still need BCM signal to rack IN03B25 to connect to Moller ADC. Additionally, we will swap the Moller ADC LV power supply with a new one, which is under test right now.

COMMENT ON RF work for 2026 HCO
Replaced and tested 2.5w amp in 2L15-3 (TWICE) and 2L19-6. Recovered and optimized RF in 2L19-6 and could only get 4Mv/m due to CWVF . Was in process of recovering RF on 2L15-3 after finding a low drive amp that I replaced last Friday. We checked all 2.5w amps and drive lines today to verify the whole drive before multiple lock -ups. 2L15-3 has good drive now but will need my RF checkout and optimizing before completing EPASS again. Good 2.5w amp checkout training to Xavier and Trey and they are Experts now. Bench checkout needs some work though.

2L19-6 Dropping with CWVF with Cavity 5 Off
Forgot to mention cavity 6 dropping with CWVF with cavity 5 still off. See that it is getting worse than last years run where it was tripping at 6 Mv/m. Don't see anything with cavity 5 history about CWVF or being limited. Running at 6.5Mv/m.

COMMENT ON SAM 2025 Box Power Supply HCO
ARC7 Box supply was ramped up to 345MeV value. Shunts were then set to their 345MeV values, and all of the shunts made it to their setpoints except MXGBS07, which will most likely need to be replaced. Diagnostic data has been taken and will be reviewed. At the moment, everything is looking good. Box supplies and shunts will be run over the night for more run time for ARC7 and all other supplies that have been readied.

Comment: 2.5 w amp replaced for second time and tested good. Drive is good but South went to Controlled before RF recovered.
