Background: Identification of radioisotopes for plastic scintillation detectors is challenging because their spectra have poor energy resolutions and lack photo peaks. To overcome this weakness, many researchers conducted radioisotope identification studies using machine learning algorithms; however, the effect data normalization on has not been addressed yet. Furthermore, learning-based identi...

Abstract An experiment aimed at searching for a sterile neutrino using new detector of the second laboratory SM-3 reactor (Dimitrovgrad, Russia) has been simulated. This is scintillation antineutrinos with multisection structure and horizontal arrangement sections. Distributions counts from prompt delayed signals, as well dependence efficiency on selected thresholds, have obtained by simulation...

Abstract The EXO-200 experiment searched for neutrinoless double-beta decay of 136 Xe with a single-phase liquid xenon detector. It used an active mass 110 kg 80.6%-enriched in ultra-low background time projection chamber ionization and scintillation detection readout. This paper describes the design performance various support systems necessary detector operation, including cryogenics, handlin...

PURPOSE In this article, we evaluate a plastic scintillation detector system for quality assurance in proton therapy using a BC-408 plastic scintillator, a commercial camera, and a computer. METHODS The basic characteristics of the system were assessed in a series of proton irradiations. The reproducibility and response to changes of dose, dose-rate, and proton energy were determined. Photogr...

Much research is being conducted on position-sensitive scintillation detectors for medical imaging, particularly for emission tomography. Monte Carlo simulations play an essential role in many of these research activities. As the scintillation process, the transport of scintillation photons through the crystal(s), and the conversion of these photons into electronic signals each have a major inf...

We consider detection of high-energy photons in PET using thick scintillation crystals. Parallax effect and multiple Compton interactions such crystals significantly reduce the accuracy of conventional detection methods. In order to estimate the photon line of flight based on photomultiplier responses, we use asymptotically optimal nonlinear techniques, implemented by feed-forward and radial ba...

This work reports on the development of the first phonon detectors based on CaMoO4 and ZnWO4 scintillating crystals for the CRESST-II experiment. In particular, a novel technique for the production of the ZnWO4 phonon detector with a separate thermometer carrier was investigated. The influence of the thermal and mechanical treatment on the scintillation light output of CaMoO4 and ZnWO4 crystals...

A 68 Ge source can be used to calibrate the positron detection eeciency of a liquid scintillation neutrino detector. A method to dissolve radioactive 68 Ge in pseudocumene-based liquid scintillator is described. The homogeneity of the source distribution has been studied and results for two Ge compounds are discussed. Light yield and light attenuation length of the liquid scintillator are not a...
