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 . The results of the neutrons observation and possible construction of the pyroelectric neutron generator are presented.\n\nThe work was supported b y a program of the ministry of education and science of The Russian Federa tion for higher education establishments\, project №14.578.21.0192 (RFME FI57816X0192).\n\nhttps://indico.particle.mephi.ru/event/4/contributions/7 65/ LOCATION:Milan Hotel Hall of the 2nd floor URL:https://indico.particle.mephi.ru/event/4/contributions/765/ END:VEVENT END:VCALENDAR
