Section: claims

1. A device for generating a hot plasma comprising: a cylindrically shaped fuel element concentrically aligned with a predetermined axis;  a linear theta pinch device concentrically aligned with said predetermined axis;  a working gas contained within said linear theta pinch device;  cylindrical plasma sheath means generated by said linear theta pinch device from said working gas for producing a theta pinch compression wave in said fuel element;  a concentric fuel element plasma layer formed by vaporization and ionization of an outer portion of said fuel element by the application of said cylindrical plasma sheath to said fuel element;  annular beam means concentrically aligned with said concentric fuel element plasma layer to dispose energy in said concentric fuel element plasma layer sufficient to ablatively drive said fuel element to produce a beam generated compression wave in said fuel element;  whereby said theta pinch compression wave and said beam generated compression wave arrive at the center of said fuel element nearly simultaneously to enhance generation of said hot plasma. 2. The device of claim 1 wherein said annular beam means comprises an annular photon beam. 3. The device of claim 1 wherein said annular means comprises an annular electron beam. 4. The device of claim 1 wherein said annular beam means comprises an annular ion beam. 5. The device of claim 1 wherein said cylindrical plasma sheath comprises a cylindrical sheath of DT plasma.
