Data taking throughout the day, evening and night with semi-stable beam at 4.0 nA.

During the day, HV mainframe hard reboot fixed the ECAL HV board (sector 5). Will need to be investigated during maintenance day.

During evening shift, reduced beam raster radius (Vpp from 2.2 V to 2.1 V). 
Raffaella installed new mon12 version in counting house. Beam is not touching bottom of target cell anymore.
Changed HWP from OUT to IN.

Beam stopped at 7:30 for Maintenance Day

Plan:
Maintenance Day started at 7:30
- Injector (horizontal Wien magnet PS) and North Linac RF work
-  Will need to do Moller run when beam returns, most likely evening shift
Polarized target work (change to deuteron material)

We will have a RC meeting today at 12 PM.
