<p>Yesterday, we were completely done with Moeller measurement around 6:00 pm. The measurement's result indicated 87% polarization. Following the measurement, we started to take data with reference cell empty. Around 8:45 pm, beam was gone because of the vacuum issues on 1L07 and two cavities, 1L04 and 1L12 refused to go in HV. We continued to take data around 3:00 am when beam was back. Once we moved to data taking with reference cell filled with N2, beam started to trip ion chambers while ramping up to 30 uA. About 1.5 hrs later, it's been decided to take 15 uA by owl SL. Around 7:10 am, beam was taken away to do harp scans and tune the beam by MCC. We restored data taking with reference cell N2 around 9 am when the harp scans (beam size) looked good. Currently, we're taking data with the reference cell in a way to give target people priority to do their AFP loss studies and temperature tests.</p>
<p>We will have an RC meeting today at 4:15 pm at the second floor of the counting house. Here is how to connect remotely:</p>
