Abstract For future MeV-scale neutrino experiments, a Cherenkov scintillation detector, CSD, is of particular interest for its capability to reconstruct both energy and direction charged particles. A type new target material, slow liquid scintillator, SlowLS, which can be used separate lights, one the options detectors. multi-hundred ton spherical CSD simulated using Geant4-based Monte Carlo so...

natural radionuclides present in soil as well as certain anthropogenic radionuclides released to the environment are the major contributors to terrestrial outdoor exposures. in the assessment of human exposures from environmental radioactivity, besides the conventional method of soil and vegetation sampling combined with laboratory based analyses of environmental media, the other choice would b...

Abstract A convolutional neural network (CNN) architecture is developed to improve the pulse shape discrimination (PSD) power of gadolinium-loaded organic liquid scintillation detector reduce fast neutron background in inverse beta decay candidate events NEOS-II data. spectrum an event constructed using a Fourier transform time domain raw waveforms and put into CNN. An early data set evaluated ...

Good optical transparency is a fundamental requirement of liquid scintillator (LS) detectors. Characterizing the to its own emitted light key parameter determine overall sensitivity large-volume detector. The attenuation in an optical-pure LS dominated by Rayleigh scattering, which poses intrinsic limit LS. This work presents spectrometric approach measuring wavelength-dependent scattering leng...
