<p><strong><span style="text-decoration: underline;">RC UPDATE</span></strong></p><p>After yesterday's maintenance day (https://logbooks.jlab.org/entry/4380941), beam checkout began at 5am this morning with harp scans (https://logbooks.jlab.org/entry/4380842) and beam centering (https://logbooks.jlab.org/entry/4380876).  At 6:15 we were ready to resume production but unable to receive any decent beam.  At the morning meeting it was decided to take beam away to flush a magnet in ARC 10 that is preventing beam delivery to Hall D.  They goal is to have beam back to A/B/D halls by 1pm and all hall running smoothly before the long holiday weekend.  We will have an RC meeting at 1pm today:https://jlab-org.zoomgov.com/j/1616220064</p><p>More details on proposed special runs, issues, work completed etc can be found here: <a href="https://sbs.jlab.org/wiki/index.php/RC_meeting_and_Run_Plan,_Thursday,_May_22nd">https://sbs.jlab.org/wiki/index.php/RC_meeting_and
