Abstract
Gamma spectrometers are used to quantify and identify
radioisotopes in the sample under test. There is a recent interest
around the world in implementing low-cost gamma spectrometers. One
of the main parts of the modern gamma spectrometer is the digital
pulse processing unit (DPP). The implementation of this unit using
advanced microcontroller chips has appeared in recent years as an
attractive approach. This is due to its advanced performance and low
cost. In this paper, we present a design flow to implement a DPP
unit using an ARM Cortex-M3-based microcontroller chip. The sodium
iodide detector is the targeted detector for this design. Our
prototype is approved experimentally to construct spectrums
comparable to commercial devices. And it can cope with input count
rates up to 45 kC/s.
