While 0L04 cavities are up I'll quickly check reproducibility in orbit, colinearlity, and transmission in CW. Afterwards I'll perform an 0R match at high energy.

ARC3 power supply and its associated shunt is running at their 345mev values. Please ramp down supply @ 9pm today. If the supply trips for any reason then please generate an op's PR with EPICS screen grabs.

Body: 

DCP has ramped ARC3 and its associated shunts to the 345MeV values. All shunt currents and voltages look good. All diagnostic signals from the box supply also look good. We will run the supply for ~4 hours to get some run time out of the supply and associated shunts.

2L02B, 2L03A, 2L03B, and 2L04A cycled open and closed.

Beamline vacuum interlocks tested:
--Upstream/Downstream interlocks for all valves verified.

--"All valves closed" external zone trigger verified when 2L02 fast valve triggered.

--Instrument Air Handle/ >60psi Pressure interlock to valves verified.

--VPG2L03A Pirani/Convectron interlock to VIP2L03A verified.

--VCG2L03A Cold Cathode interlock to VIP2L03A startup verified (New protocol implementation for zones with extra gauging)
----- Interlock kicks in after ion pump overload fault.

With all lasers enabled in BOOM Buddy, I did another QE scan, this time with the C laser, for good measure.

Wrote QE output (CSV) to: /cs/prohome/fileio/b/beamQEScan/data/F1-0/scans/qe_scan_2026-02-13T16:43:23.228705.csv

I applied power in all the cavities that are available in 1L05 and didn't see any gradient in any of them
probe cables were connected this morning and not sure what is causing this. It should be checked Monday
