coordinated with RF, cryo, and I&C VAC to safely swap the fan tray for IOCNL2. We restored the IOC and the MOPS and cryo said everything recovered correctly after the job finished around 10:30ish. Swapped filters in ARC buildings leaving only the halls left for voltage measurement and filter replacement. Thank you Robert (cryo), Evonda (RF), and Leo/Matt A(I&C VAC) for the assistance.

swapped 0L04 after finding inx1S01 to be in spec and inx1s02 doesn't actually exist. repurposed the electrometer slated for 1s01/1s02 for 0L04/0L05 and swapped it after lunch. Reset settings and ramped EXT bias. going to let it run over night and check in the morning.

The task was performed by James Donaldson, Scott Windam, Bob May and myself, along with assistance from RadCon's Stephen Kennell and Zach Giunti. This also was cross training to hand off these calibrations to AESIC. All went well and as planned. The H2 Sensors in Buildings 91 & 95 are within spec.
