Do not bypass this cavity until RF can T/S and restore klystron KCCU and correct KMAI on tube. This cavity has been GSET several times for the Low Energy run but was bypassed 05/30/26 by operator for filament board which is not what the problem is. We need the klystron to have filaments and we need to be in RF permit to correct the klystron and restore it correctly for the high energy run when we get back to power/beam permit to T/S !! Not the filament board as you can see !

Cavity was un-bypassed 06/02/26 after cavity was recovered and GSET 0 for low energy run since 06/25 run several times this year. Klystron was recovered for KMAI after several times of KCCU being recovered and then GSET 0 again by operators for no CRFP and bad filament board.

Work done in the South Linac(West & East Arc) today:
Dead Pump at VIP7R10.
Will update the CED whenever it is accessible again.

Replaced Ion Pak for:
VIP2L01 (Reading high still, probably will need to be changed out will give it a day to see if it gets better)
VIP3R10A
VIP7A24
VIP7A26
VIP7A30
VIP2A08

Verified Readbacks for:
VIP1R10A (high due to adjacent pumps, came back down)
VIP9R07A (high due to adjacent pumps, might be a small leak in the area)

Now that the injector is going back to high power I reinstalled the imager. Checked the motors from the service building. Ops confirmed the camera was working at ~12:30 but it doesn't seem to be entirely working now. I can change the setting but cannot load the video.

The high voltage is still at zero for the NDX units at NL24 and NL25 connected to the I400 at NL24B11. Need to restore it before the start of C100 operations.

OM22 tested while under bypass with the assistance of MCC SSO. It responded as expected and can be returned to service.

Only time this cavity had filament and RF was from 4/24/26 to 4/26/26 and then it had no filaments and erroneous RF GMES after several attempts to restore. Starting from scratch and replacing the RFCM and then the filament bd. again today after unbypassing and finding filaments at 0v. Replaced RFCM and fixed No filament voltage KFVM but cavity will need to be restored to RF and GMES problem when we get back to POWER/BEAM Permit.

After power cycle, there were a couple ion pump power supplies and multiple cold cathode gauges that needed to be manually restarted.
iocnl1diag needed to be power cycled, but recovered after power cycle.
iocnl1b needed to be manipulated from the console (thanks Erik!) to be resuscitated.
Mike M. told me that Frank is going to be installing supplemental pumping around 1L06 so I'm leaving the valves closed in that area, Ops can open them as needed.
