<p>In the past 24 hours<br />
* Last night the TO called me and informed that there is ESR problem and requested to contact and inform ESR.<br />
So far, we used to call the crew chief with such a request. Yesterday, I suggested the to make halog entry and request the crew-chief; and the TO contacted the crew-chief with such a request.<br />
Later in the morning, the crew-chief stopped by the CH and told the shift worker that Hall/RC should contact the guard or the Cryo directly.<br />
I brought this up during the 7:45 am RC meeting and Doug will follow up with this and will update us.</p>
<p>* We ran smoothly yesterday until the ESR problem occurred this morning - <a href="https://logbooks.jlab.org/entry/4430380">https://logbooks.jlab.org/entry/4430380</a>.<br />
* We were forced to decrease current to 12 uA. We continued with that until beam studies started around 5:30 am - <a href="https://logbooks.jlab.org/entry/4430448">https://logbooks.jlab.org/entry/4430448</a><br />
* There were two ECal heater controller resets - one during swing and another during owl - <a href="https://logbooks.jlab.org/entry/4430334">https://logbooks.jlab.org/entry/4430334</a><br />
* There were few events where DAQ rate went to zero due to busy signal from crates. Problems were solved by remote resets only.</p>
<p>Since yesterday's Day to today's owl: ABU - 16.8 hr, BANU - 1.8 hr, BNA - 2.7 hr.<br />
* Total Accumulated Charge at Kin3 so far: 69.5 C (Goal: 100 C)<br />
* Total Accumulated Charge at Kin3 since yesterday : 1.2 C</p>
<p>Updates from MCC:<br />
* Today is maintenance day - planning close accelerator around 2 pm.<br />
* Most likely, the next Wednesday will be a beam studies day. </p>
<p>Current Issues and Hall activities:<br />
* DAQ startup sometimes problematic. Also the RCGUI freezes frequently.<br />
* CDet VME crate is not working (People are inside the Hall to fix this) - <a href="https://logbooks.jlab.org/entry/4426917">https://logbooks.jlab.org/entry/4426917</a><br />
* Jiwan and Ben are planning to work on HCal VTP firmware fix.</p>
