Agenda:

1- 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.

2- Today's beam study

  1. IA scans at different helicity generator settings to verify 240 Hz modes work as expected.
