摘要

Pyroelectric crystals were used to achieve D-D fusion through the ionization and acceleration of D2 gas molecules into a deuterated target. The primary focus of the research presented here was to improve the mechanisms of ionization, enhance reproducibility, and increase neutron production. A thermal management system was developed using two thermoelectric module controllers with a feedback loop and new heat sinks. A portable, prototype system was also tested and used to achieve reproducible neutron yields of 1.2 x 10 4 (+/- 1.8 x 103) neutrons per thermal cycle. The thermal management system provided the ability to reduce the thermal cycle time by a factor of 2 compared to previous experiments. In order to improve the D2 gas ionization, tungsten nanorods were deposited on the crystal surface and, with a single tip glued to the center of the nanorods, experiments produced 4 times more neutrons than using nanorods or a single tip alone. In addition to furthering the basic understanding of pyroelectric crystal-driven fusion processes, this work also provides information necessary to achieve reproducibility that may ultimately lead to the development of a portable, battery-operated neutron generator.
