Agenda:

1- Two major MOLLER beam studies in Hall A - Hall A is ON April 5th:

1. FFB in Hall A: (tentatively scheduled on April 17)
   1. BSList to start Hall A April run with FFB ON [1] and for MOLLER test [2]- Ryan Bodestein
   2. BSList to measure PQB beam in Hall A helicity flip of 2 kHz and to measure monitor (BPMs, BCMs) resolution: [3]
2. K-Long Beam Loading: (tentatively scheduled on May 1)
   1. BSList to deliver 15.6 MHz beam from Hall D laser to Hall C - Riad Suleiman: [4]
   2. BSList to measure PQB beam in Injector and Hall A - Caryn Palatchi: [5]
   3. Other issues to look for:
      1. 4-channel BPMs saturation in West Arc
      2. Dumping beam harmonics right onto one of the higher order mode frequencies

2- Fix Hall D Tune-Mode-Generator; it has low extinction ratio
