The Best Choice of High Purity Germanium (HPGe) Detector

below and are based on some basic concepts about how the detection process works, how gamma rays penetrate materials, and the principles of gamma-ray spectroscopy. Unresolved choice issues can be reduced to a level where they have little or no impact on the resultant performance of the spectrometry system. This document explains how you can easily make a wise, well-informed choice. We assume you already have a basic knowledge of HPGe detector terminology and that you also have a basic knowledge of gamma-ray spectrometry. If you need to review these areas, refer to Reference 1 or 2 for a good introduction.
