Back to Background Rate Studies
Detector Configuration
- Double-Hit Resolution: 250 ns
- Threshold: 1 keV
- Strip Threshold: 5 mV
- Maximum Number of Hits: 100
- Dead Zone Radius: 3.5 cm
Items for Discussion
- These rates seem incredibly high.
- Is the maximum number of hits coded into the simulation sufficient for the FDC? If it is applied at the event level, 100 hits is probably not enough.
- How relevant is the increased background as a function of downstream position of the package?
- Does this need to be considered when optimizing package placement?
- Do/Should the dead regions for each package vary in size depending on downstream location?
