Detector
Dose rate estimations for PbWO4 detector at 4m from target, at 1uA, and for a 10-cm long target
Scattering Chamber Information:
- outer diameter = 45 inches
- inner diameter = 43.125 inches
- distance beam line to SHMS window = 1.25 inches
So for a point target, the minimum angle is 58 mr or 3.4 degrees. For an extended target you will need to adjust, it becomes about 4 degree for a 15 cm target. So assume 3.5 degrees as rough number.
