Abstract
Abstract The generation of intense burst of high energy electrons and/or intense currents of positive ions is accomplished by compressing a magnetic field in the presence of a gas plasma. The gas plasma is contained in a metallic cylinder and the magnetic field is established by means of a capacitor bank driven current that flows in the axial direction on the metallic cylinder and returns through the gas plasma contained in the cylinder. Detonation of explosive material surrounding the metallic cylinder drives the cylinder walls inward effecting compression of the magnetic field and a concomitant increase in plasma current.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
122 words
An explosively driven plasma current generator comprising a cylindrical member of conductive material, means for generating a magnetic field within said cylindrical member, an end plate of conductive material connected to effect electrically and hermetically tight closure of one end of said cylindrical member, a partial end plate disposed within and spaced from the distal end of said cylindrical member effecting electrically tight closure thereof, insulating means disposed on the inner surface of said cylindrical member and in combination with said partial end plate effecting hermetically tight closure of the distal end of said cylindrical member, gas plasma disposed within said cylindrical member, explosive means disposed around the outer peripheral surface of said cylindrical member, and means for detonating said explosive means.
Claim 2
Dependent Claim
