Abstract: A method of generating an output gas, comprising plasmatizing an input gas with RF power propagating from a tip of an electrode to form an annular plasma sheath constrained by a tube with said RF power propagating within said annular plasma sheath; and forming said output gas as said annular plasma sheath propagates away from said tip of said electrode.

Abstract: A plasma generating device utilizes a cold plasma to contain and direct a stream of electrons with a hand held nozzle to enhance healing of wounds and skin surface abnormalities, and to kill pathogens on skin surfaces in humans and animals wounds, abnormalities and pathogens.

Abstract: A coaxial energy delivery system comprised of a radio frequency power supply as the preferred source of power, electron accelerator system, and electrically conductive tube to be fitted to permit the flow of a gas intended to be energized as a plasma, a point of discharge of the said gas, whether in tubular or columnar form, coincident with the point of emission of the electromagnetic wave, the emission of said electromagnetic wave at said point, utilization of a fraction of the potential energy at that point to form a plasma in such gas flow which plasma forms a conduit or waveguide to insulate and confine the electromagnetic wave in its interior, which is manifested as a visible beam in appearance and thereby directing such coherent electromagnetic wave to a target material to be coupled with such material and impart its energy thereto.
