Chopper vacuum spike correlations to xB current terminated on MS

I've noticed that all instances of the IN02B11 rack mismatches are associated with the vacuum spikes in the chopper region. These spikes have happened with no beam, and without magnet mismatches, but seem more frequent when there is beam. Therefore solving the vacuum problem would probably solve the rack problem.

In addition, the vacuum's background rates in the chopper region are corresponded exactly to hall B's current (see figure 3). The spikes also happen less when hall B isn't on, which could mean that the terminated current on the master slit is poorly affecting vacuum.

While sending CW so we have a zeropos in the Halls before turning off and getting zeropos to the dumplettes.

Follow-up Re: Connections outside the control room pausing energy locks

Deniability suffers when the darn Elock GUI clearly shows it was me. I was making short fudgeIt (new) runs to study the algorithm's calculations. These write nothing to the control system, but I forgot they still suspend the locks for the short time I run to dump data. I will disable the lock suspension while I continue to study the algorithm in preparation for this evening's MCC test time.

Connections outside the control room pausing energy locks

We looked up and saw that the energy locks were paused, and did not know what was happening. We double checked to make sure we weren't running anything that would halt them, and no one was.

The client connections shows a client running FudgeIt, which will automatically pause energy locks.

Please notify/contact us before testing applications that may change operating conditions in the control room!
