HPGe-Compton Net: a physics-guided CNN for fast gamma spectra analysis via Compton region learning

High-purity germanium (HPGe) detectors have been golden standard for gamma spectrometry in low-level radioactive waste (LLW) analysis; however, their notable shortcoming is prolonged measurement durations for weak radioactive waste materials. The present study aimed to develop the HPGe-Compton Net, a 1D physics-guided convolutional neural network to accelerate LLW analysis by taking advantage of the entire response function of a HPGe detector …
