Paper Abstract

Gamma-ray spectroscopic systems with high efficiency and energy resolution have become important in many fields. Conventional systems with analog shaping are more and more replaced by digital systems that can provide higher throughput, better energy resolution and better stability. We present the development of our new versatile real time Multi Channel Analyzer with digital signal processing, the GMCA. The device has two independent channels and is compatible with various detectors like Coplanar Grid (Cd,Zn)Te, HPGe, LaBr3, NaI and CsI. Different sensors for temperature, pressure and humidity provide additional information and allow the correction of thermal drifts. We show energy resolution measurements and compare spectra measured with different detectors connected to our system and to commercial systems both analog and digital.
