Problems
1.Calculate the spatial resolution of a position sensitive detector having a pitch
of 40μmand working in digital mode.2.Estimate the change in spatial resolution of a semiconductor microstrip detec-
tor if the readout scheme is changed from all strips to every third strip.3.Calculate the effective quantum yield of a CCD camera having quantum effi-
ciency of 40% and conversion efficiency of 87%.4.Determine the change in the dynamic range of a CCD if its ADC resolution is
changed from 12 bits to 16 bits. Assume that all other parameters remain the
same.5.Compute the dynamic range of a silicon based CCD system at an energy of 1.5
keV. The system has a gain of 20 photoelectrons per ADC count and 16-bit
ADC resolution.6.What would be the dynamic range of the CCD camera described in the previous
exercise for an absorbed energy of 10MeV?
