Back to Background Rate Studies
Detector Configuration
- Double-Hit Resolution: 75 ns
- Threshold: 2 MeV (30 MeV in repository)
- Maximum Number of Hits: 500 (100 in repository)
Items for Discussion
- Change threshold and maximum number of hits in repository.
- GlueX note under development to describe mechanism for background suppression in the FCAL. Timing information from the FADC will be key in removing background hits.
- At what dose does radiation damage begin to become an issue?
Plots
The background rates in Hz for each block in the FCAL.
The total radiation dose per second in the FCAL. This calculation assumes uniform deposition of energy throughout the block. This is not actually correct since, for example, the upstream end of the block will receive a higher dose than the downstream end.
