CORRECTION: This would be minimally invasive as described *if* it were possible to lock the muxer BPM by BPM. It's not. Locking the muxer affects an entire IOC's worth of BPMs. We are backing away from doing any pass locking for this test.

Interlock checks for MMA1H01 Box supply have been completed. Spoke with the work coordinator for Hall A and received verbal approval to energize and run the power supply. Before running the supply, we verified in the hall that the magnet leads were still covered and tested the magnet beacon. The power supply has been turned back on, and beacon operability was verified when the supply output is at ~30 A. Higher current testing will be performed tomorrow with front panel diagnostics and screenshots. PTW and IC have been completed.
