| Abstract: | A new approach to develop a source of 2.45 MeV neutrons caused by polarization reversal in KD2PO4 single crystal (DKDP) during its passage through the Curie point (Tc = 220 K) is presented. The background of this approach is referred to observation of neutron/proton emission in DKDP during paraelectric–ferroelectric phase transition to spontaneous polarization state (and vise versa) upon the heating/cooling of crystal through Curie point Tc = 220 K. The proposed source is based on earlier established proof of deuteron acceleration and neutron generation in the crystalline lattice of ferroelectrics during their transition to spontaneously polarized state (polarization reversal). In order to obtain neutron yield for practical application, the proposed solution foresees a separate DKDP crystals serving as cathode and anode and undergo to simultaneous ferroelectric phase transition in low-pressure deuterium atmosphere. | |
