D-D nuclear fusion using different size pyroelectric crystals

Abstract

Theory predicts electrons play a detrimental role in creating the conditions for D-D fusion in pyroelectric crystal accelerators. Three different pyroelectric crystal sizes were paired in six different configurations to determine if experimental results agree with theory. An experimental configuration using a 30 mm diameter tip crystal opposite a 20 mm diameter target crystal yielded better neutron results than a 20 mm diameter tip crystal versus a 30 mm diameter target crystal as predicted by theory. Two 20 mm diameter by 20 mm thick lithium tantalate crystals yielded ~1 × 10 4 neutrons per thermal cycle.
