− | === Roadmap toward a decision for Bcal Readout===
| |
− | #Technical specifications, already outlined in [http://argus.phys.uregina.ca/cgi-bin/private/DocDB/ShowDocument?docid=795 GlueX-doc-795]
| |
− | #* [http://www.jlab.org/Hall-D/sipm_dev SiPM tests are underway]
| |
− | #* Werner has recent results of tests of fine mesh PMTs reported in [http://argus.phys.uregina.ca/cgi-bin/private/DocDB/ShowDocument?docid=1173 GlueX-doc-1173]
| |
− | # 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 in [http://argus.phys.uregina.ca/cgi-bin/private/DocDB/ShowDocument?docid=1077 GlueX-doc-1077]
| |
− | #* 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.
| |
− | #* [[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).
| |
− | # Detailed B-field plots including dependence on B-field components
| |
− | #* [http://argus.phys.uregina.ca/cgi-bin/private/DocDB/ShowDocument?docid=912 Magnetic fields at the location of detector pmts]
