Daily Summary March 4-5

Somewhat better than the previous 24 hours. Hall A is off. 11.5 hours ABU.

Day: Beam off due to RF problems. We made an access to fix the DC HV problem (thank you, Morgan!) and the FT Chiller high temperature (again thank you, Morgan!!). Other than that waited for beam (only a few trickles).

Swing: Beam back around 7 p.m. - started data taking on ND3 +pol with HW plate out. Late in the shift switched HWP IN, and Hall A graciously performed their equalizer script. After that continued data taking. 

Owl: Quiet data taking. Target polarization is slowly decaying (now only 38%, consistent with trigger bit asymmetry). 

PLAN: No RC meeting today. On Monday Day shift, we will switch to C target as soon as the target group is available. Take data on C until Maintenance day TUESDAY (note it has been moved up).
