Options for readout of the Bcal using existing technologies
- Readout of the barrel calorimeter based on conventional photomultiplier tubes (GlueX-doc-832, Jun 2007)
- Issues that need to be considered (rough outline)
- light guides and collection
- light detector
- magnetic fringe fields / shielding
- cabling / number and sizes of cables / signal degradation
- dark box / "wrapping of detector"
- impact on photon reconstruction [what is our current geometry?]
- cost estimates
- Comments:
- Area of fibers cover 50% of the area of the end of the Bcal. Reduction is 2.
- Area of the output of the WC (1.2 cm2) reduces the readout by 4cm2/1.2cm2 = 3.3.
- The Sketch below is to illustrate the space constraints for any light collection and readout system:
