Roadmap toward decisions
- Technical specifications, already outlined in GlueX-doc-795
- SiPM tests are underway
- Werner has recent results of tests of fine mesh PMTs
- 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.
- Detail description of cables and electronics on each detector
- 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.
- Resolution
- Complete simulation studies for correct thresholds for the FM.
- Studies of timing resolution. Realistic simulation for both photons and charged particles
- Resolution for various geometry options (mentioned above).
- Detailed B-field plots including dependence on B-field components
- Dynamic range required, especially for near pmt/small angle showers.
