Yesterday day shift was a rocky time for the accelerator. Last minute restricted access for hall C and B for dry runs of the Energy Secretary tour tomorrow were followed up a cryo trip which took beam down for most of the day shift (<span style="color: rgb(0, 0, 238);"><a style="color: rgb(0, 0, 238);" class="OWAAutoLink" id="OWAbf11cc90-b4b7-5cb4-9c8d-14394109bcb1" href="https://ace.jlab.org/dtm/all-events?qualified=true&incidentId=16138">https://ace.jlab.org/dtm/all-events?qualified=true&incidentId=16138</a></span>),
followed by some scattered downtimes during the first half of swing shift. Beam initially came back around 5 but was spotty, shift crew attempted to do cross check during this time and were able to complete it around 7, beam finally stabilized around 9 and
ran smooth through the OWL shift. During this time, we continued taking production data on LH2 with 15 uA beam. During late swing/early OWL, Vidura continued work on the GEM gas mixture (<span style="color: rgb(0, 0, 238);"><a style="color: rgb(0, 0, 238);" class="OWAAutoLink" id="OWAf2c3839e-479e-6fdf-4603-6cff4eb52fce" href="https://logbooks.jlab.org/entry/4446454">https://logbooks.jlab.org/entry/4446454</a></span>),
and yesterday day Jhih-Ying changed come hot channels on ECal (<span style="color: rgb(0, 0, 238);"><a style="color: rgb(0, 0, 238);" class="OWAAutoLink" id="OWA347dff03-b0e7-e236-6022-f08a147083b7" href="https://logbooks.jlab.org/entry/4445944">https://logbooks.jlab.org/entry/4445944</a></span>).
The current run plan is to continue taking production data at 15 uA on LH2.</div>

Today is RF recovery day, MCC will not be opening up any of the injector, north & south linacs, or or BSY. They plan to be done by around 2:30 this afternoon, and are hoping to deliver beam sometime mid swing (7:30 or so). Halls B and D have requested rapid
and controlled access for this time, hall C will be moving to restricted access. Hall A is scheduled to be surveyed at 10:00 this morning for controlled access, with the intent to lock up around 2:00.</div>
