Agenda:

1. Beam Schedule:
   1. Monday Dec 7 during Day: Tune beam delivered to Hall A dumplette in Beam Switch Yard (BSY) at 11 GeV
   2. Tuesday Dec 8 at 3:00 pm: Hall A closes
   3. Wednesday Dec 9 – Friday Dec 11: CW beam to Hall A dump (including a full eight-hour run at 80 µA (900 kW))
   4. Friday Dec 11 during day: Start Hall D setup
   5. Friday Dec 11 – Monday Dec 21: Beam to Hall A dump and Hall D (including a full eight-hour run at 80 µA to Hall A and 5 µA to Hall D)
   6. Friday Dec 18 – Saturday Dec 19: 5-pass 11 GeV Mott vs Moeller/Compton (spin dance to study spin-precession in presence of synchrotron radiation)
   7. Saturday Dec 19 – Sunday Dec 20: 1-pass 2.2 GeV Mott vs Moeller/Compton (spin dance to study spin-precession with no synchrotron radiation)
2. Scaler and EPICS variables for the Halo Monitor are ready and tested with pulsers. EPICS data can be shared with MCC. Waiting to connect Halo Monitor signals to discriminators and then to these scalers.

Notes from this meeting:

• Halo monitor signals AA, BB, CC, DD are cabled to scaler channels 1,6,7,8 via 30 mV threshold discriminator and correspond to epics variables aline_halo1,2,3,4 respectively.
