Good news: We've got beam in Hall C since 4am this morning. Accelerator managed to get the beam transport issues under control last night by switching from RF to magnetic horizontal separation. This allowed them to bring up Halls A/B/C. Since then, we have been executing the run plan (GEM latency scan, optics runs). Data taking is proceeding smoothly. We will be busy with this until at least the end of SWING. Currently, MCC has no plans to stop beam delivery today.

The main open issue in the hall is the HMS Q2 power supply, which interlocks on ramp-up. A plan how to move forward is under consideration. If there is a longer beam down-time today (>=2 hrs), we may want to take Controlled Access to let the tech team continue troubleshooting.

We will have a RC meeting today from 2:30–3:00pm on the second floor of the counting house and on Zoom. See https://logbooks.jlab.org/entry/4346862.
