Crew Chief Shift Log, 2026-06-02 DAY
Start of shift: Injector in RA, NL and SL survey on going.
COMMENT ON RF Repairs for the High Power Run
2L04-3 Replaced filament board and 50 ohm resistor
2L04-6 Replaced filament board
1L11-5 Replaced filament board
1L15-3 Replaced 50 ohm resistor
Won't know for sure how effective these fixes were until we have power permit back, so keeping PTWs on issue. -kepler, schoene, msmith, alexs

Measured the db readings for the BCM system fibers from BSY and E2 to the Injector. The readings are as follows;
Base reading for the meter with adapters and patch cables for all tests = -22, -23 db
System A
E2 to Injector = -22, -23 db
BSY to Injector = -23, -24 db
System B
E2 to Injector = -23, -24 db
BSY to Injector = -22, -24 db

2L09-1 GSET 0 by OPS for Large Detune angle
This cavity was restored on 04/21/2026 with CWVF and KRRP onset at 11.8 Mv/m so I lowered the ODVH to 10 Mv/m and it was having problems after 4 days and GSET 0 by the operator who stated a Large Detune Angle when trying to OLT it. Going to set the ODVH to 6 Mv/m and try to recover it as soon as we are back into Permit to try RF again. Leave GSET 0 until RF can look at it and restore.
