Thanks to Jiwan for performing the beam restoration task! One thing during the beam restoration yesterday swing is that the MCC found our Moller quads were on for the past three weeks, which are supposed to be off. After a few unsuccessful trials delivering our desired beam spot size, MCC turned off Moller quads ( <a class="external free" href="https://logbooks.jlab.org/entry/4097518" rel="nofollow">https://logbooks.jlab.org/entry/4097518</a> ). After that, MCC still have troubles delivering our desired beam spot size (320 - 350 on target), We talked with Yves, Gordon, Arun, Bill, and Simona and agreed that we should accept the current result ( <a class="external free" href="https://logbooks.jlab.org/entry/4097607" rel="nofollow">https://logbooks.jlab.org/entry/4097607</a> ). Please refer to a more detailed log from Iuliia ( <a class="external free" href="https://logbooks.jlab.org/entry/4097400" rel="nofollow">https://logbooks.jlab.org/entry/4097400</a> )</li><li>After beam restoration, we did a carbon hole check, we found the hole in the right position with the previous beam position, no scan was needed, see the carbon hole ( <a class="external free" href="https://logbooks.jlab.org/entry/4097641" rel="nofollow">https://logbooks.jlab.org/entry/4097641</a> )</li><li>Resumed data taking on He3 target, 36 uA Beam, in the owl shift</li></ul><h1><span id="Short_Term_Run_Plan" class="mw-headline">Short Term Run Plan</span></h1><ul><li>Continue production run on He3 target, 36 uA</li><li>Use GEnII-noSBSGEMs DAQ config</li><li>Use ps3=0, ps5=6, others =-1</li><li>BBCal threshold at -366 mV, HCal threshold at -19 mV</li><li>NMR measurement every 3 - 4 hours, close to 4 hours is better</li></ul><h1><span id="Planned_Accesses_to_the_Hall" class="mw-headline">Planned Accesses to the Hall</span></h1><ul><li>Access for hodoscope</li><li>Access for GEM BB APV will need a further evaluation see if it's necessary</li></ul><h1><span id="Special_Requests" class="mw-headline">Special Requests</span></h1><ul><li>None</li></ul><h1><span id="Notices_in_Effect_for_Shift_Crew" class="mw-headline">Notices in Effect for Shift Crew</span></h1><ul><li>Power down SBS, BB, and Detector HV before making an access to the Hall</li></ul><h1><span id="Data_Collection_Status" class="mw-headline">Data Collection Status</span></h1><ul><li>73 out of 141 days (51.7%)</li><li>Uncorrected accumulated charge on He3: 45.588 C out of 232C (19.65%)</li></ul><p> </p> </div>
