Organization

  • Time: 4 pm EST
  • Connecting: detailed instructions are here
  • Conference id: 536076821

References

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
