ABSTRACT:
A method and apparatus for improving the energy resolution, sensitivity and other aspects of a x-ray or gamma ray detector by using modified acquisition electronics in conjunction with low leakage current photodiodes. Specifically, increasing the integration time of the sample circuits without degrading energy resolution due to parallel noise in order to improve energy resolution and sensitivity, and to allow new electronics designs.
