Action Items

• Send Todd a geometry of tagger area, including the mapped tagger magnet field, for GEANT simulations (Richard). Richard is working to update the defined geometry based on a drawing received from Tim, Richard will add field map from Dan Sober
• 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.
• Alexandre will meet with RadCon next week to coordinate details of accessing monitor information
