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.
