<div>This is the RC summary for Day Shift July 20 to Owl shift July 21.</div><div> </div><div>Overally good production data taking on Deuterium at 325nA in the last 24h.</div><div> </div><div>During Day shift, Nathan fixed the Solenoid and Torus DAQ recording issue by moving the files to a different disc (<a href="https://logbooks.jlab.org/entry/4422613">https://logbooks.jlab.org/entry/4422613</a>). The local discs were nearly full due to a problem with the tape driver (<a href="https://logbooks.jlab.org/entry/4422699">https://logbooks.jlab.org/entry/4422699</a>) which is fixed now. Otherwise the target was purged and some rocs needed reboot.</div><div> </div><div>During Swing shift, beam was pretty good and we had to reboot some rocs (adcecal3, adcpcal1) and cycle ATOF which tripped. In addition, the shift worker noted a missing LTCC PMT in the monitoring plots  but HV looks okay. Notified Youri which referred to Mauri. More investigation on Monday. The m
 issing P
 MT was there at least for a day.</div><div> </div><div>During Owl shift at 4:20am Torus and Solenoid tripped and we are off since. It is traced back to a tripped Torus IOC which partly controls valves. During the day the IOC was rebooted in the hall and both magnets are recovering now. </div><div> </div><div> </div><div>ABU for last 24h</div><div> </div><div>- 15.5h of ABUs ~ 65% efficiency,</div><div> </div><div>- Total ABUs since April 5th: 1119.5+15.5= 1135 --> 1135 / (75.5 * 24) = 62.6% </div><div> </div><div>- Day 107 of 151 scheduled: 107/151=70.9%</div><div> </div><div>- BANU: 4.5h due to Magnet trips, Target purge and Roc reboots</div><div> </div><div>Plan for the next days:</div><div> </div><div>- Short beam checkout after magnets are back</div><div>- Production data on deuterium at 325nA until Wednesday </div><div>- Switch to He on Wednesday</div><div> </div><div> </div><div> </div><div>&
