After steering in SL to lower the board temperature for MDB2L26V, the trip rate has gone down noticeably.

MBD2L26V was identified as possibly overheating and contributing to 7S01 BLM trips. The setpoint current was reduced from -8 to -1.5 A (10 A trim), which did significantly cool off the magnet (figure 1), but trashed the upper pass linac orbits, particularly in the north linac. Vertical west arc recombiner steering in arcs 4,6, and 8 eventually landed us back in a stable steering solution (figure 2), with IDX readings almost completely quiet with 5 uA tune beam to the hall D dumplette (figure 3).

If you have not done so, please reach out to ACG to see if we can make this tool available. It is needed to troubleshoot vertical oscillation as seen on 2A SLM and noted at 3C12 bpm.
