Agenda:

1- Parity DAQ runs with every pattern to confirm pattern sequence. Checked patterns and delays with beam (Arindam Sen): media:beam_study_asen.pdf

2- Initial data to study correlation with K-Long charge asymmetry - Repeat with more statistics. Need to do SCL measurements with Hall D laser.

3- Two major MOLLER beam studies in April:

  1. FFB in Hall A: we want to start Hall A April run with FFB ON. Then, we will need 1-shift of beam studies to the hall at helicity flip of 2 kHz. We will also measure monitor resolution (new bpms, bcms).
  2. K-Long beam loading: we want 1-shift of beam studies with K-Long beam (5 uA low-rep rate) to Hall C and 40 uA to Hall A.
