<p><strong>Update on day and swing shifts of April 18 and owl shift of April 19 </strong></p><p><strong>CEBAF status</strong>:</p><ul><li>Stable beam during day shift (https://logbooks.jlab.org/entry/3562915). 7.0 hours of available beam time. </li><li>Problem with 5th pass separator during swing shift (https://logbooks.jlab.org/entry/3563210). 4.0 hours of available beam time. </li><li>Stable beam during owl shift (https://logbooks.jlab.org/entry/3563063). 6.3 hours of available beam time. </li><li>Beam studies planned for Monday, April 23. </li><li>RF recovery planned for Tuesday, April 24.</li></ul><p><strong>Hall C status</strong>:</p><ul><li>Hall C is configured for the SIDIS experiment (E12-09-017). The HMS is setup for detecting electrons (inclusive measurement) and the SHMS is setup for detecting charged pions and kaons (semi-inclusive measurment). Details on the experimental setup are available on: https://hallcweb.jlab.org/wiki/index.php/E12-09-017_Run_P
 lan#Experimental_setup </li><li>For various theta angles in the HMS, the beam current is reduced significantly to keep the pTRIG1 rate below 500kHz. </li><li>Problems with SHMS rotation during day shift (https://logbooks.jlab.org/entry/3562845).</li></ul><p><strong>Data taking</strong>:</p><ul><li>The detailed plan is available on: https://hallcweb.jlab.org/wiki/index.php/E12-09-017_Run_Plan </li><li>For kinematic setting 1, we have completed 10 out of 14 measurements. </li><li>We have completed kinematic setting 2. </li><li>The data taking of the SIDIS experiment with various configuration changes between the runs requires three persons on shift. We have many open slots in the shift schedule (https://misportal.jlab.org/mis/physics/shiftSchedule/?experimentRunId=HALLC-2017-2018), in particular for the owl shift of the coming weekend and next week. We need more volunteers for shifts. </li></ul><p><strong>Hall C Daily RC meeting</strong>: We will meet tod
 ay at 1:30 p.m. in the conference room locat!
 ed on the second floor of the counting house. Remote participation will be possible via Blue Jeans (Meeting ID: 543903672).
