Abstract
En 中文
This study demonstrated neutron generation using a laser-heated pyroelectric crystal under low-pressure D2 conditions. A LiTaO3 crystal was heated using a 1047 nm Nd:YLF laser to induce a pyroelectric effect, generating a high electric field that accelerated the excess compensating charge and D 2+ . Numerical calculations based on Monte Carlo simulations were used to evaluate the ion trajectories, scattering events, and neutron yield as functions of D2 pressure and electrode gap. The experiments confirmed neutron production without the use of tips or multiple crystals, achieving a simple and miniaturized structure. The maximum neutron yield of approximately 4.5 & times; 102 n s-1 was observed at 0.3 Pa, which was consistent with the theoretical predictions. These results indicate that a compact neutron source can be realized using laser heated pyroelectric crystals, offering potential applications in confined environments.
