Description
Detection of low energy neutrino is a challenging task for advanced
studies of coherent neutrino scattering processes or for the observation
of neutrino magnetic momentum. For this purpose, the detector must be
capable to register the deposited energies starting from a hundred of
eV. One of the option is the development of CsI(pure) scintillation
detector operating at the temperature of liquid nitrogen. It is known,
that this scintillator could achieve the record light yield of about 120
thousand photons per one MeV of deposited energy. It means that 100 eV
energy deposition corresponds to 12 photons, that can be detected by
advanced photodetectors.In this work we present the performance of
small CsI(pure) scintillation cell which is readout by compact silicon
photomultiplers (SiPM) with high detection efficiency. The SiPM thermal
noises and the achieved light collection efficiency are presented. It
will be shown that signal of about 30 photoelectrons/keV is attainable
in such configuration of detector.
