Swing Shift Summary

Leader: Sarah Phillips
Target: Pete Markowitz
Third: Min Huang

Summary

We did production running until 9:00pm, when James and Josh came in and did a target anneal. While they were doing that, John Musson did some work on the BPMs. Then we went back to production running for the rest of the shift.

Timeline

16:00 - Shift starts with production running, with Runs 5805 and 24509 on-going. The right arm needs about 20 more minutes of data; Left arm needs about 5-6 hours of more data.
16:05 - MCC is taking away the beam for about 30 minutes to do some beam studies for Hall B.
16:21 - Beam is back. We are starting our next run.
16:30 - The beam positions, current, and energy are all wandering around. I call MCC, and they say that they are trying to clean up Hall B's beam, and that they will adjust ours.
17:28 - We are changing the momentum on the right arm to the next setting (from 1.4684 to 1.3509). The left is unchanged. We are also changing from the bottom NH3 target to the top one (and polarizing it).
17:34 - MCC called. We are changing our target, but they wanted us to know that the beam will be down for a few minutes while they bring up the C100 cavities in the south linac. They expect that this will reduce the trip rate.
17:48 - Our target is ready, but MCC isn't. I called for an update, and they say 5 or 10 minutes.
17:54 - 50 nA restored to Hall A. Not very stable, so we are waiting to start the left (the right is still settling).
18:06 - The beam has become more stable, so we are starting production running on the left.
20:49 - The target guys (James and Josh) have invaded the counting house and taken over the target for an anneal. I called for a controlled access (with a full survey) so people can do work on the the BPMs.
22:04 - Hall C flips the IHWP to OUT!
22:30 - The survey of the hall is finished, and a copy of the survey map was dropped off in the counting house.
22:54 - James and Josh have the target up at 80% polarization, so I called down to the hall to see if they are almost done. They are, and will be out soon.
23:18 - Back to beam permit! Back to production running!
23:35 - Beam is back.
23:40 - CODA reboot!
24:00 - End of shift! Production running!

Notes for the next shift:

Keep an eye on the energy; the value was wandering a little earlier.
We didn't do a bleed-through measurement, since Hall C wasn't on most of the swing shift, so it is up to the owl shift to make up for it!
Hall C is now in control of the IHWP, so keep track of when they flip it. Ideally, you want an ihwp flip about halfway through each point. If they don't flip it for some reason, make sure that you do.
Do a dilution run for each point
Do 2/3 with the right arm before moving to the next point.
Keep an eye on the beam current so it doesn't drift down to 40 nA. Keep and eye on the beam positions too.
If MCC cannot deliver beam due to an FSD on the Moller target when you know the target is out, ask them to reboot the IOC.
