Agenda:

  1. Results from December 2015 Hall A beam test
  2. Plans for Spring 2016 beam test in Hall A
  3. Spring 2016 Beam Schedule:
    1. Accelerator Restoration: January 28 – February 04
    2. Hall A – 11 GeV, 50 µA polarized beam: February 04 – April 14



Notes from this meeting:

  • Problem with few BPMs signals observed in December 2015 with CW beam around 30 µA was traced to bad RF modules giving abnormal signals during High to Low

Gain transition. The EPICS position readout also went bad, not just the S/H card signals. The faulty RF modules are being replaced (IPM1C12 already replaced).
