Summary

Production running!

Timeline

16:00 - Shift starts with no beam, with MCC about to send beam back.
16:05 - We have beam back, and are statring production running! We are resuming 1.1937 on the right and are starting 1.3509 on the left. The IHWP is in.
17:09 - The IHWP is now OUT!
17:16 - We haven't had beam for about 15 minutes. MCC says it is because they are bringing up some other cavities in the north linac to reduce the trip rate, and they estimate it will be another 15 minutes.
17:25 - Beam is coming back!
17:32 - The beam is pretty unstable so far. Lots of trips, but we are starting our runs. The first parts of runs 5857 and 24554 may have some unstable beam.
18:53 - Finished production running on thee left for 1.3509, so we are moving the target to home to start the dilution runs.
18:59 - Starting our first dilution run for this setting.
19:08 - Starting diluation run with Carbon
19:18 - Moving to the dummy target (cross hairs) to do the dilution run.
19:32 - Changing the momentum on both arms! Left goes from 1.3509 to 1.2698, and the right goes from 1.1937 to 1.1220.
19:39 - The left has settled, so we are starting the dilution runs on the left for this new momentum settting of 1.2698 on the dummy target (cross hairs).
19:49 - Now doing the dilution run with the carbon target with the left for the 1.2698 setting.
19:51 - Moving the target to the home position to do the dilution run at this momentum setting. Since the right has settled, we'll do that too.
20:09 - Moving to the bottom NH3 cell!
20:31 - Requested 50 nA! Starting production running!
22:10 - The IHWP is now IN!
22:53 - Changing the left arms from 1.2698 to 1.1937!
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.
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.
