Cooldown of 2L26 is complete.

Struggled to get liquid in it, I recall that this module was previously having difficulty maintaining liquid and had it's JT around ~100% open when cold. Likely has a thermal short somewhere contributing to the high heat leak.

Either way, its cold now and is filling to 20%

the view is quite off, had to put MBL0L02 at a very small value. 38530 BDL was nominal orbit here.

Zeroed BPMs specified in procedure, found beam on the viewer using MBF0L06, cycled spectrometer, nudged it up a few hundred BdL, and cycled again. Fig. 3 is the final energy measurement of 115.77 MeV.

Going back and checking phasing, It seems that 0L02-8 was phased before 0L02-7, which made all of the difference necessary to bring energy to the full 116 MeV.

The cooldown for 2L24 has finished. LL set to 20%, with JT at 20%-80% range. Shield outlet still continues to cooldown.

Lockout of 2L11 and 2L20 CPS completed for SRF work. Filament bd. replaced in 1L09-4 to fix filaments but no KCCU noted in Beam Permit. Need to look at klystron resistor or T/S. Filament board was also replaced in 0L04-3 but it still had original Filament Voltage High fault and only ~.54a vice ~3.5a like the others. Board connections and voltage ramp at tube looked good. Klystron filament needs further T/S. Techs: C. Kerns and X. Gomez
