DC Power noted that the rack room in the North Access building is very hot. This is not good for the trim cards in that room. The door to that room has been propped open as a mitigation but this is not a permanent solution. Additionally, the temp readback in that room doesn't appear to be representative of the actual temperature (see figure 1).

Zone is off in preparation for North Linac survey. Vacuum seems roughly stable but bouncing off the turn-on threshold for the pump, so I put it in local and am keeping it off for now.

Set Lem Req RF Heat by checking a hypothetical LEM at 990, and setting it from the cryo load. Had to cut the gradient ramp short to open up NL.

We were able to make it to the previous set points, and then we pushed to see if we could get to the ODVH. For the most part, no issues. Waveguide pressure has slowly climbed and is very slowly recover. Beamline vacuum is also increasing. It may be worth continuing to push gradient here.
