Action Items

• Estimate rates and ranges of parameters needed for the photon beam tuning (Todd for accelerator; Elton, Hovanes, Eugene, Alexandre for Hall D)
  • Need rates for profiler, start counter, ps
• Richard will provide a "sacrificial" board with 30 SiPMs to register neutron damage during initial electron beam tune.
• Hovanes is preparing photomultipliers that can be used to measure beam loss along the beamline.
• Complete the tagger layout with the expected configuration for the fall running, including all shielding. (Tim, Chuck, Elton)
