Roadmap toward a decision for Bcal Readout

Status and schedules can be found in the report at the Jan collaboration meeting.

  1. Technical specifications, already outlined in GlueX-doc-795
  2. Geometry, especially related to acceptance gap between Bcal and Fcal. Detailed plan should be developed.
    • Light guides and inactive material is different for the two options. We need to simulate the effect of each
    • Precise configuration of light guides for FM pmts on the upstream end, where the field at the end of the Bcal exceeds 0.5 T. See light guides studies.
    • Detail description of cables and electronics on each detector
  3. Granularity.
    • Optimization of distribution between inner and outer detectors
    • Which detectors should have discriminators and TDCs
    • Study of signal splitting, choice of discriminator - has an impact on number of cables.
  4. Resolution
    • Impact of dark rate on resolution
    • Light collection
    • Complete simulation studies for correct thresholds for the FM.
    • Energy threshold for various assumed PDE and DR combinations.
    • Studies of timing resolution. Realistic simulation for both photons and charged particles
    • Resolution for various geometry options (mentioned above).
  5. Detailed B-field plots including dependence on B-field components
  6. Dynamic range required, especially for near pmt/small angle showers.
  7. Private:Readout Cost Estimates
