Back to Background Rate Studies

Detector Configuration

  • Double-Hit Resolution: 250 ns
  • Threshold: 1 keV
  • Maximum Number of Hits (per Event): 100

Items for Discussion

  • Should stereo geometry be so noticeable in background rate? If the noise source is far upstream, then stereo straws will present a large cross section to the noise source than axial straws.

Plots

The average background rate per straw in Hz as a function of ring number in the CDC.
A double-log plot of the energy of all hits in the CDC. The spectrum cuts off at 1 keV due to the GEANT threshold.
