- ПубликацияТолько метаданныеParameters of a fine-grained scintillator detector prototype with 3D WLS fiber readout for a T2K ND280 neutrino active target(2019) Mineev, O.; Blondel, A.; Fedotov, S.; Khotjantsev, A.; Kudenko, Y.; Куденко, Юрий Григорьевич© 2018 Elsevier B.V. An upgrade of the long baseline neutrino experiment T2K near detector ND280 is currently being designed. The upgrade program includes the development a new highly granular fully active scintillator neutrino detector as a neutrino target. The baseline concept of the detector represents an array of about 2×106 small scintillator cubes each of 1 cm3. The 3D signal readout from each cube is provided by three orthogonal 1.0 mm Kuraray Y11 multiclad WLS fibers read out by SiPMs. A small prototype of the detector assembled of 125 cubes was tested in a beam of charged particles as well as with cosmic muons. Obtained parameters of the prototype are reported in this paper.
- ПубликацияТолько метаданные3D SuperFGD detector for the T2K experiment(2022) Dergacheva, A.; Khotjantsev, A.; Kudenko, Y.; Mefodiev, A.; Куденко, Юрий ГригорьевичThis paper describes the instrumental aspects of the novel fully active 3D fine-grained scintillator detector SuperFGD as a main part of the Near off-axis Detector Upgrade Program of the T2K experiment. © 2022 Elsevier B.V.
- ПубликацияТолько метаданныеDevelopment and tests of WLS plates for Outer Detector of Hyper-Kamiokande(2023) Kudenko, Y.; Khotjantsev, A.; Mineev, O.; Yershov, N.; Куденко, Юрий ГригорьевичThis paper describes measurements of photosensing units developed for the Outer Detector of Hyper-Kamiokande to increase the effective acceptance of Cherenkov radiation. The photosensing unit consists of a photomultiplier and a wavelength shifting plate optically coupled to it. Plates doped with different fluors and covered by different reflectors were tested using UV LED light sources in air and water. The effects of wavelength shifting fluors, side reflectors, water interface, and shaping of optical coupling are studied. Results of measurements of the light yield and its uniformity are presented. © 2022 Elsevier B.V.
