- 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
- segmentation of 30
