Abstract
A high-powered microwave torch provides a tunable cavity to move between a first and second mode for ignition and steady-state operation. The tuning may be accomplished by adjusting end plates of a cylindrical cavity consistent with a desired TE01δ resonant mode. A swirl promoting spacer system allows cantilevered coaxial tubes to accommodate gas flow rates, and a junction between the tube assembly and a plasma nozzle provides a compression engagement resistant to temperature-expansion induced stress.
