++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
16:00 Begin shift with beam restoration in progress.
16:03 Turn VDCs on.
16:04 Move target to Loop1 LD2.
16:13 Begin Q2 measurement runs.
16:35 Noticed that left HRS rates are a factor of 10 lower than expected.
16:41 VDCs turned off.
16:43 Ask for 100 uA to check rates. MCC only gives us 95 uA.
16:45 Noticed that left Q1 polarity is wrong.
17:30 Left Q1 back up after polarity toggle.
18:00 After beam trips increased, MCC lowered our current to 90 uA.

22:14 MCC bumps our current up to 99 uA. Beam has been very stable!
