# Compton suppression in BEGe detectors by digital pulse shape analysis

## TL;DR

This paper introduces a digital pulse shape analysis method for BEGe detectors that significantly reduces Compton background in gamma ray spectrometry, improving peak-to-continuum ratios.

## Contribution

A novel pulse shape discrimination technique based on rise time analysis for BEGe detectors that enhances Compton suppression capabilities.

## Key findings

- Peak to Compton ratio improved by over two times for 60Co.
- Cs-Peak to Co-Compton ratio increased by more than three times.
- Method verified through experiments with 60Co and 137Cs sources.

## Abstract

A new method of pulse shape discrimination (PSD) for BEGe detectors is developed to suppress Compton-continuum by digital pulse shape analysis (PSA), which helps reduce the Compton background level in gamma ray spectrometry. A decision parameter related to the rise time of a pulse shape was presented. The method was verified by experiments using 60Co and 137Cs sources. The result indicated that the 60Co Peak to Compton ratio and the Cs-Peak to Co-Compton ratio could be improved by more than two and three times, respectively.
