The output of X-ray semiconductor pixel detectors such as Medipix2 depends on various effects, such as the primary energy distribution inside the sensor layer, the diffusion of the generated charge carriers during the drift, the discrimination of the input signal by a threshold, and detection of scattered quanta originating from the detector parts behind the sensor layer. In this study we introduce an advanced Monte Carlo simulation including all these effects. The simulation was verified for energy distribution functions by performing threshold scans of monoenergetic radiation with the Medipix2. (c) 2007 Elsevier B.V. All rights reserved.
