HIGH EFFICIENCY 4-PI NEGATRON BETA-3 PARTICLE EMISSION SOURCE FABRICATION AND ITS USE AS AN ELECTRODE IN A SELF-CHARGED HIGH-VOLTAGE CAPACITOR

摘要

The present invention is directed to an encapsulated β⁻ particle emitter that comprises a sol-gel derived core that comprises a β⁻-emitting radioisotope and an encapsulant enclosing the core through which at least some of the β⁻ emissions from the β⁻-emitting radioisotope pass, wherein the encapsulant comprises a substrate and a cover and at least a portion of the encapsulant is electrically conductive, and a method for making the same. Additionally, the present invention is directed to a capacitor comprising such an encapsulated β⁻ particle emitter and a method of performing work with such a capacitor.
