Pyroelectric crystals, such as LiNbO3 or LiTaO3 being under influence of temperature gradient produce electric field up to 106 kV/cm. It was experimentally confirmed that the crystal installed in the chamber with residual gas pressure about 1 mTorr can be used for generation of X-Rays*, electrons** and neutrons***. The unique property to generate high potential without external high voltage power supply can be used to develop compact electron and ion accelerators with particles energies up to several hundred keV for different applications. We have developed the laboratory experimental setup for exciting d-d nuclear fusion by pyroelectric crystal LiTaO3. The setup allows to provide and control the neutrons generated during d-d nuclear fusion. It is shown that the neutrons with energy 2.45 MeV can be generated starting from a level of electric potential generated 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.
