Improvement of accuracy in radioactivity assessment of medical linear accelerator through self-absorption correction in HPGe detector

Nuclear Engineering and Technology
Medical linear accelerators with an energy of 8 MV or higher are radiated owing to photonuclear reactions and neutron capture reactions. It is necessary to quantitatively evaluate the concentration of radioactive isotopes when replacing or disposing them.

Semiempirical Efficiency Calibration in Semiconductor HPGe Gamma-Ray Spectroscopy

Journal of Spectroscopy, 2018
One of the main problems in quantitative gamma-ray spectroscopy is the determination of detection efficiency, for different energies, source-detector geometries, and composition of samples or sources.

Assessment of the inactive dead layer thickness of old high-purity germanium detector: A study by Monte Carlo simulations and experimental verification

Radiation Protection and Environment, 2017
High-purity germanium (HPGe) detectors are commonly used for high-resolution gamma spectrometry. A HPGe detector considered for this study was in continuous operation for the past 15 years in our laboratory.

Simulation of Structural Effects on Detection Efficiency in P-Type Coaxial High-Purity Germanium Detectors Using the Monte Carlo Method

Journal of Isotopes
Determining the full-energy peak efficiency (FEPE) of a high-purity germanium (HPGe) detector through experimental methods or Monte Carlo (MC) simulations is crucial for accurate radionuclide quantification. This study presents a meticulously constructed

Angular distribution measurement of gamma rays from inelastic neutron scattering on 56Fe at the nELBE time-of-flight facility

EPJ Web of Conferences, 2017
Inelastic neutron scattering from 56Fe was studied at the nELBE time-of-flight facility. The incoming neutron energy ranges from 100 keV to 10 MeV in the fast neutron spectrum, where high precision nuclear data are needed.

Machine learning-powered data cleaning for LEGEND: a semi-supervised approach using affinity propagation and support vector machines

Machine Learning: Science and Technology
Neutrinoless double-beta decay ( $0\nu\beta\beta$ ) is a rare nuclear process that, if observed, will provide insight into the nature of neutrinos and help explain the matter-antimatter asymmetry in the Universe.
