Simulated and experimental results are presented from a silicon X-ray pixel detector which is bump bonded to a PAC5 pixel array of read-out electronics. When coupled to a matching, fully depleted silicon detector the pre-amplifier is observed to have a linear response up to 80 keV, and a pulse height resolution of around 1 keV FWHM over the range 13–60 keV. The Monte-Carlo N-Particle code has been used to simulate the detector response under illumination from a variety of energies. The excellent agreement observed between simulation and experiment illustrates the predictive abilities of such packages.
