Abstract
A remote microwave plasma generator comprises the combination of two parts, a tunable microwave applicator, and a double wall, water cooled quartz/sapphire tube. The tunable waveguide applicator is a nonconducting adjustable waveguide short with a quartz/sapphire tube inserted through it. The adjustable end is one quarter of a guide wavelength from the center line of the tube, and the other side is 0.1 inches less in distance, thus permitting the applicator to be used with a triple stub tuner for optimum coupling.
