It was experimentally confirmed that the crystal i nstalled in the chamber with residual gas pressure about 1 mTorr can be us ed for generation of X-Rays [1]\, electrons [2] and neutrons [3]. Due to t he unique properties such as On/Off mode of operation and absence of radio active materials pyroelectric generators seems to be promising tool for ca libration of neutrino and dark matter detectors [4\,5].\n\nWe have develop ed the laboratory experimental setup for development of pyroelectric neutr on generator for calibration of neutrino and dark matter detectors [5]. Th e setup allows providing and controlling the neutrons generation process r ealized during d-d nuclear fusion. It is shown that the neutrons with ener gy 2.45 MeV can be generated starting from a level of electric potential g enerated by pyroelectric crystal about 30 kV\, in contrast to the typical neutron tubes which need the applied outer high voltage level about 100 kV .

To identify reliably the neutrino events a thoro ugh calculation of the atmospheric neutrino background should be performed . We calculate the atmospheric neutrino spectra in the energy range of 100 GeV - 10 PeV using the set of the hadronic models and several parametriz ations of cosmic ray spectra supported by experimental data. It is shown t hat rare decays of short-lived neutral kaons contribute close to one third of the atmospheric conventional electron neutrinos at the energies above 100 TeV. The account for kaons production in pion-nucleus collisions gives rise to increase the $\\nu_{e}$ flux by 5–7% in the energy range of 1 00 GeV – 100 TeV. The detailed comparison of our calculations performe d with use of $Z(E\,h)$ -functions approach [2]\, with those of MCEq me thod by A.Fedynitch et al. [3]\, shows the consistency on the whole at l east in the energy range 100 GeV – 1 PeV. Calculated neutrino spectra a gree rather well with the measurement data of the experiments IceCube [4\,5] and ANTARES [6]. Uncertainties of the measurement data above 400 TeV leave a window for the the QGSM prompt neutrino component [2].\n\n [1] Aartsen M.G. et al. (IceCube Collaboration).
