All power fed from the 40MVA substation will be put onto the 33MVA substation Wednesday Morning beginning at ~7am.

Work has been coordinated by FML (powers/kujawa) with Operations (Suhring) and Cryo (Creel). FML has walked every loop, identified the break points, and have discussed the plan. FML is convinced there will be no interruption to power at any point in the process.

Once power and loads are removed from the 40MVA, the meter can be safely replaced.

Task Approved.

Les Richardson and I check the trim cards in E1, E2, E3 and E4 for any B8 mod Analog Blocks in the machine. We pulled (8) trim cards with the B8 mod on them.

7-cell was causing some issues this morning, it wouldn't stay in GDR mode, it kept
quenching. We kept walking down the gradient to see if that was the issue. Decided
to contact an expert -- Tomasz came in to take a look at things -- turned out the POFF
just needed to be optimized. It was off by ~10deg. 7-cell is back up and running!

MBHK101H current readback was very unstable -- tried reseating the card, no dice -- card was swapped.

MHBM502H was mismatched and wouldn't take setpoint -- tried reseating, no dice -- card was swapped.

Also having issues with MHBM904AH not responding -- it's possible the hardward in the cave isn't wired correctly. We may have to go into the cave to check things out. Will update when more information is available.

After turning back ON DecaRad HV, field emission levels on the gun are similar to those observed since the last time the gun delivered beam at 200kV.

Magnet rack ITF02 tripped off when Kiarra swapped a board, don't know why. But this took down the gun because the dipole bend magnet went to zero, or unresolved, or something. Ramping the gun back up. But at least this seemed to fix the first steering magnet, MBHK101H, now in agreement with setpoint request. We were able to turn the magnet rack back ON via epics

DecaRad HV seems to have been off since 10/17/20 at 12:00 (Figure 1).

Now that DecaRad HV has been turned back on, probe readings seem to be reporting as normal (0-8 CPS) with the gun turned off (Figure 2)

Tomasz coaxed the 7 cell back to life, hooray. With a small amount of steering associated with the inadvertant spot move, beam arrives at M504 viewer. Now time to lens center and quad center.

Don't know the exact beam momentum but GSets are the same as before. Beam bouncing on viewer M504, magnet mismatch issues, perhaps. Kiarra is swapping trim cards
