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
