3-D rendering of scintillator bars

cross-section through barrel, 30-fold segmentation shown

SiPM readout concept (PDF)

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
inner surface of scintillator at 73 mm from centerline
- segmentation of 30
- scintillator width at inner surface = 15.35 mm
- scintillator width at outer surface = 15.98 mm
plastic package width = 3.85 mm
- times 4 -> 15.40 mm
