Cherenkov Detector Details

Helium Drift Chamber

  • K/proton separation not shown but is included in the study.
  • Separation between Pions & Kaons as a function of momentum.
    • Theta dependence changes above 12 degrees but is not shown (not super large).

Gas Threshold (Original Design)

  • From ~1 or ~0 to 10 degrees
  • No K/proton separation
  • Separation between Pions & Kaons as a function of momentum.
    • Theta dependence is present but not shown (not super large).
    • NOTE: Cut NOT performed when #sigmas < 3.0!!

HBRICH

  • From ~1 or ~0 to 20 degrees
  • K/proton separation not shown but is included in the study.
  • Separation between Pions & Kaons as a function of momentum.
    • Theta dependence is present but not shown (not super large).

LHCb RICH

  • BIG IMPORTANT NOTE: These studies were performed with the parameters of the LHCb RICH AS IS (at a ~$4 million cost)
  • From 0 to 20 degrees
  • 99.3% K/Pi separation from 0.6 to 2.6 GeV/c
  • Perfect K/Pi separation above 2.6 GeV/c
  • 99.3% K/proton separation from 2.0 to 10.0 GeV/c
  • Perfect K/proton separation above 10.0 GeV/c
