CIS activities:
- Beam QE scan and spot move with on-call staff training: summary by Marcy #4537606. Submitted the draft procedure to Kathy for finalization.
- tunnel access with Facilities to plan for a new penetration in the laser room wall

Charge lifetime: can't interpret the most recent data yet as the spot move happened only yesterday. But, assuming we get a lifetime similar to before, the new spot position should last us through the run.

Task did not happen during Tuesday's MD - Manpower diverted to emergency response elsewhere.
This is a high priority task - WA LCW pump currently in operation has developed bearing / coupling noise and vibration and should be taken out of service as soon as reasonably possible.

This is in regards to the linked tuning downtime.

We are still running into 3R10 blm trips. We've tried numerous steering solutions and we'll think we've solved it for a bit and then the blm trips will pop back up. Optics on-call is here helping usdiagnose the problem. We will try to steer for 15 more minutes and if we can't find an answer we'll download an allsave from before the 3R10 blm issues started popping up and see if that puts us in a better place.

I don't think this is the cause of the trips, but it should be on design either way.

Even Orbit Lock BPM issue Diagnosis Update

Log Number: 4538011Logbook(s):

INCLOG

Entry Makers: sethgBody:

I am investigating the even orbit locks causing steering issues. IPM2A05, 6A04, 8A04, and AA04 BPM (iocw3se1) is locking onto a signal when beam is not present and is producing extreme oscillating position (5mm) swings when running Tune Mode @ ~4.8uA. I believe the noise that is being locked onto is swamping the true Tune Mode beam signal. When they are running Tune Mode Beam and when Beam is OFF the YGAIN values are within 20 counts of each other this is not normal of course. This is where I believe the problem resides.

Replaced arc det. PMT in 1L14-7 that was failing manual arc tests. After verifying voltages at interface chassis, tested good 3 times. Also replaced arc detector on 1L04-2 that had been knocked off during maintenance. Examined tube and didn't see damage so I rehung it and it also tested good x3.
