Abstract

See full text

A plasma-arc vaporization chamber includes features configured to permit very high-energy plasmas, preferably with high hydrogen content. The vaporization chamber includes a female electrode having an internal chamber with a target region made of a conductive material highly resistant to thermal degradation and an isthmus region of sufficient width to slow plasma flow therethrough enough to permit vaporization within the internal chamber of a material delivered into the plasma. The material is preferably injected at an angle counter to the flow of the plasma. The vaporization chamber also includes a flange-cooling chamber adjacent to a flange of the female electrode. Additionally, the chamber preferably includes vortexing gas injectors configured to provide a helical gas flow within at least a portion of the internal chamber.
