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!

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> ).
