<p>Since yesterday's RC we have been fairly productive. We started the GEM commissioning plan during SWING but had to end early to put in the sieve slit. During OWL we completed the optics program. Today we swapped out the carbon foils with 1 mm holes for ones with 2 mm holes. We believe the reason we were unable to image the hole yesterday was because the 1 sigma beam spot size at the target is 0.5 mm. When inspecting the foils it was clear from the burn marks that we were on the hole (see https://logbooks.jlab.org/entry/4053901).</p><p>Today I requested we move the hall reconfiguration to Wednesday because we still have a lot to accomplish with the remaining time at one-pass.  The table below is the run plan for the rest of the commisioning period which we can discuss at todays RC meeting.  We will meet at 3:15 (after the weekly Hall C meeting)</p><p> </p><p>Time: Daily at 3:00pm<br> Location: Counting house conference room</p><p>Join ZoomGov Meeting<br> <a !
