  • High efficiency 4-? negatron ?-3 particle emission source fabrication and its use as an electrode in a self-charged high-voltage capacitor
    Patent number: 8134275
    Abstract: The present invention is directed to an encapsulated ?? particle emitter that comprises a sol-gel derived core that comprises a ??-emitting radioisotope and an encapsulant enclosing the core through which at least some of the ?? emissions from the ??-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 ?? particle emitter and a method of performing work with such a capacitor.
