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 yo...

High purity germanium detector in gamma-ray spectrometry

We measured full energy peak efficiency of High-Purity Germanium detector which is important for gamma-ray spectrometry experiments. A brief but very effective description on the basic formation of detector crystal and creation of signal pulse has been presented here. This article is furnished in such a way that the contents find useful and interesting to physics and electronics students, educa...

Precise efficiency calibration of an HPGe detector: source measurements and Monte Carlo calculations with sub-percent precision.

With the goal of measuring precise gamma-ray intensities for short-lived (< 5 s) accelerator-produced activities, we have calibrated the efficiency of an HPGe detector between 53 and 1836keV to sub-percent precision with a combination of source measurements and Monte Carlo calculations. Using known or independently measured detector dimensions, we have achieved both relative and absolute agreem...

MONTE CARLO SIMULATION OF P-TYPE HPGe DETECTORS – THE DEAD LAYER PROBLEM

The Monte Carlo method is increasingly applied for simulation of germanium detectors. It can be successfully used for the evaluation of full energy peak efficiency or of the efficiency corrections due to self-attenuation, coincidence summing and geometry effects. Usually the simulation task is to evaluate the energy deposited in the sensitive volume of the detector, assuming that the detector s...
