Abstract Experiments searching for the neutrinoless double beta decay in $$^{76}$$ 76 Ge are currently achieving lowest background level and, connection with excellent energy resolution of germanium detectors, they exhibit best discovery potential decay. Expansion to a ton ...
Abstract Experiments to search for neutrinoless double-beta (0 νββ ) decay of 76 Ge using a high-purity germanium (HPGe) detector rely heavily on background suppression technologies enhance their sensitivities. In this work, we proposed pulse-shape analysis method based neural network (NN) and light gradient boosting machine (lightGBM; LGB) discriminate single-electron (background) double-elect...
High-purity germanium (HPGe) single crystals find their applications as radiation detectors especially for spectroscopy of high-energy photons and particles in nuclear physics. Growing “detector-grade” HPGe crystals, with tailored structural defects controlled impurity content, uniform throughout the crystal is a challenging task this type crystalline semiconductor material. All different proce...
One of the most important instruments in gamma ray spectroscopy is HPGe detector. Concept of virtual point detector was considered for Ge(Li) detector. On the basis of this concept, there is a point inside a Ge detector that can be regarded as a fictitious point detector hosting all the interactions. If there is really a point whose response can be considered similar to that of the whole real b...
We report on the first experimental demonstration of Compton imaging of gamma rays with a single coaxial high-purity germanium (HPGe) detector. This imaging capability is realized by two-dimensional segmentation of the outside contact in combination with digital pulse-shape analysis, which enables to image gamma rays in 4p without employing a collimator. We are able to demonstrate the ability t...
The Monte Carlo method was used to determine full energy efficiency of a high-purity germanium (HPGe) coaxial detector within an energy range of 53.2-2614 keV. Also, measurement was carried out for a standard Marinelli beaker of 600cm3, which was placed into the reference material of mixed gamma. The plot of the experimentally derived effic...
