ABSTRACT:
In an energy spectroscopy system in which the photon detector such as a germanium detector provides pulses indicative of incident gamma or x-ray radiation, compensation circuitry corrects the amplified pulse output for charge trapping effects in the detector. The compensated output is provided to a prior art multichannel analyzer. The compensation circuit adds to the detected pulse a correction factor proportional to a polynomial function of charge collection time of the carrier being trapped multiplied by the amplitude of the pulse. In this manner, the output pulse is increased to compensate for impediments to charged carrier migration within the structure of the detector, and resolution is improved.
