(a) The probability of different orders of pulse pileup for paralyzable and varied pulse shape models. P(0) is the fraction free of pileup, P(1), P(2) and P(3) are the first, second, and third orders of pileup, respectively. (b) Count rate performance for paralyzable and varied pulse shape models. (c) Fraction free of pileup under different photon fluxes. To obtain good statistics, 1 million incident photons are simulated. The simulated detector has a thickness of 300 μm, pitch of 25 μm, strip length of 1 cm, and bias voltage of 50 V.
