[Hallc_running] [New Logentry] Hall C RC Update: July 12, 2025

The target cooldown went well yesterday, and we were taking data on LH2 (in the 20 cm LAD cell) by early swing shift.  We had hoped to run at 0.6 uA, but found the rates too high (the GEMs tripped) so we backed off to 0.5 uA and have been running efficiently at that current.

Hao noticed that SHMS 2Y13- is missing since we came back (https://logbooks.jlab.org/entry/4416177) and as of this morning it has not recovered.  I'll poke around in the electronics room and see if pushing on cables helps.

This morning, we plan to rotate the HMS to 17.0 degrees at 11 am.  We will continue taking data on LH2 at this setting until the end of the run.

I do not plan to have an RC meeting today, although we will likely have one tomorrow (Sunday) just to make sure there aren't any last minute issues or tests to address before the LAD run ends Monday morning (at 8 am).
