Abstract
A method allowing single photon counting with additional energy information without increasing the radiation dose is presented. On a pixel chip an energy window has been realised by introducing a second discriminator with a separate counter in every pixel. Both discriminators have an independent threshold voltage and can be adjusted individually. Measurements on the noise behavior, threshold variation and threshold settings are presented
