Abstract: A solid mixture of fullerene and titanium hydride, a method of its formation, and a method of its use to rapidly produce a gaseous mixture of molecular hydrogen and fullerene on demand. The solid mixture may be resistively heated by discharge of a high power electrical current from a capacitor bank through the mixture to produce the mixture of hydrogen and fullerene within a few tens of microseconds. The resulting gaseous mixture of hydrogen and fullerene may be ionized and accelerated for the purpose of mitigating electromagnetic disruptions in a magnetically confined plasma.

Abstract: A method and apparatus for rapidly producing a plasma jet on demand. A particular application is the production of such a jet and its injection into a magnetically confined target plasma for the purpose of mitigating an emerging disruption event. The apparatus includes a gas source cartridge having concentric inner and outer electrically nonconductive containment tubes, which contain a solid mixture of titanium hydride and fullerene in the annular cylindrical volume between them. The mixture is resistively heated by application of a high power electrical current to produce a gaseous mixture of hydrogen and fullerene within a few tens of microseconds. The resulting mixture of hydrogen and fullerene is introduced radially into an accelerator tube passing through the gas cartridge, where the gas mixture is ionized, accelerated and injected as a plasma jet into the target plasma.

Abstract: A method and apparatus for producing soft x-ray laser radiation. A low pressure plasma column is created by electric discharge or by laser excitation inside a rotating containment tube. Rotation of the plasma is induced by viscous drag caused by rotation of the tube, or by magnetically driven rotation of the plasma as it is created in a plasma gun in the presence of an axial magnetic field, or both. A high power electrical discharge is then passed axially through the rotating plasma column to produce a rapidly rising axial current, resulting in z-pinch compression of the rotating plasma column, with resultant stimulated emission of soft x-ray radiation in the axial direction. A rotating containment tube used in combination with magnetically driven rotation of the plasma column results in a concave electron density profile that results in reduced wall ablation and also reduced refraction losses of the soft x-rays.

Abstract: A method and apparatus for producing soft x-ray laser radiation based on z-pinch compression of a rotating low pressure plasma column are disclosed. A rotating, low pressure plasma column is created by electric discharge or by laser excitation inside a containment tube. Rotation of the plasma may be induced by viscous drag caused by rotation of the tube, or by magnetically driven rotation of the plasma as it is created in a plasma gun in the presence of an axial magnetic field, or both. A high power electrical discharge is then passed axially through the rotating plasma column to produce a rapidly rising axial current, resulting in z-pinch compression of the rotating plasma column radially inwardly with resultant stimulated emission of soft x-ray radiation in the axial direction.

Abstract: A system for creating an image of the internal features of an object includes an X-ray source and detector array positioned to interpose the object between the X-ray source and the detector array. An X-ray beam is passed through the object along a first path. While passing through the object, the beam is successively filtered twice, each time with a different filter. The successive filtration of the beam results in the production of two electrical signals by the detector which are processed to create an image signal for the path. The process is repeated for a plurality of paths through the object and the resulting image signals are combined using traditional computer tomography techniques to produce a composite image of the object.
