  • outer diameter of scattering chamber: 3.72″
    • radius = 4.7244 cm
  • inner diameter of CDC: 6.89″
    • radius = 8.7503 cm
  • scintillator thickness = 3 mm
  • for a nominal radius of 7.5 cm (roughly that in the Monte Carlo)
    • segmentation of 30
      • scintillator width = 15.7 mm
    • segmentation of 40
      • scintillator width = 11.8 mm
