Abstract: The present invention relates to a gamma-electric cell for producing a high-output voltage from a source of radiation wherein the gamma-electric cell includes a central collector constructed of a dense metal and with the central collector encapsulated within an outer layer of dielectric material. A further conductive layer is then disposed on or within the dielectric material so as to provide for a high voltage output between the conductive layer and the central collector upon the reception of radiation by the gamma-electric cell. The invention also includes the use of a plurality of collectors radiating from the central collector throughout the dielectric material so as to increase the collection area and thereby increase the current and/or output voltage. Other aspects of the invention are directed to the method of producing a high voltage output gamma-electric cell by encapsulation techniques using a dielectric material which is castable and curable so as to provide for an intimate contact between the collectors and the dielectric material which surrounds and encapsulates the collectors. Other aspects of the method of encapsulation of the present invention include the use of specific dielectric materials and also the elimination of trapped gases within the dielectric material.

Show all 9 claims
    1. A method of producing a high output voltage from a source of radiation such as gamma rays, including the steps of:
  • providing a dense conducting collector,
  • providing a plurality of metal collectors radiating from the dense conducting collector,
  • encapsulating the conducting collector and the plurality of metal collectors with a dielectric material and with the dielectric material producing a scattering of electrons in accordance with the reception of the radiation and with the dense conducting collector collecting at least a portion of the scattered electrons, and
  • connecting an electrical lead to the collector to provide a high output
