Retracted A1. PB can stay on, the comparison should still work.
VWien off for now, MFX2I01 = 208, MFX1I03 = 196.
MFX0I01 = 0.
HWien is still limited to 60 degrees pending DRVH adjustment, so "on" means 60 degrees today.

Measuring beam size on 0I02 viewer for HWien on/off as a function of MFG1I04 setpoints under the constraint that B = -A, avoiding coupling for now.

Spoke with Greg Marble.

Greg, with additional SRFVAC support, will begin Monday morning swapping five ion pumps: VIP2C00A, VIPAT09, and VIP3C{01,03,03A}. VIP3C04 is elevated but still in the "green" range. Swapping the upstream pumps will bring it down even further. VIPAT09 is railed even after the earlier nT-VIP swaps, and with its closeness to the others makes good sense to address together with the 2C and 3C ones.

Anticipates this job taking 2-3 days. This works fine, even if it spills over another day or two.

Supply going into thermal cycling and over-temping since last Tuesdays replacement. Ready spare is at zone 2L25 ready to install.

I appreciate the initiative but need more information before you can proceed.
* The original list of ion pumps was VIP3C {01,03,03A, and 04} -- why are we including AT09 now? The stretch goal was VIP2C00A, is that no longer in plan?
* Once you begin, how long do you anticipate having cleanrooms up? There is a VIP tour coming through Monday 2/16, with a dry run occurring Thursday 2/12. Would this interfere with the vacuum work that has to be done?

Replaced the klystron Sorenson PS Tuesday after it was over-temping and shutting off. Came back on after replacing it with 15.6a, instead of ~ 31.3a. Might need to replace it again for this current readback problem that the last unit didn't have. Rechecked all cable connections and didn't see a problem.

HV cables for VIP2L25B and for Waveguides 1 thru 7 have been plugged in and are showing good readbacks upstairs/epics.
VIP2L258 HV cable looks to have been rad damaged and will need to be re-terminated.

That will be done on a separate ATLis/epas next week.

Before 2L25 cryomodule was installed I load tested the HV cables for each pump. VIP2L258 showed to be overloading with nothing connected to it. This is indicative of rad damaged cable and will need to be re-terminated. An ATLis and epas will be made for the week to be done next week.
