Optimization and validation of HPGE detector efficiency calibration using Monte Carlo, LabSOCS simulations, and experimental measurements

Abstract

This research presents a novel calibration approach for high-purity germanium detectors in gamma-ray spectrometry. By integrating advanced simulation tools and experimental validation, the study achieves precise efficiency calibration without relying on multiple radioactive sources. The innovative use of LabSOCS and Monte Carlo simulations optimizes calibration, compensating for self-attenuation and coincidence summing effects. Results demonstrate strong agreement with certified reference values, confirming the method’s accuracy. This approach advances calibration practices by offering a reliable and source-efficient solution for gamma-ray spectrometry, ensuring enhanced precision in radionuclide quantification.
