FIGS. 7A and 7B provide a first, relatively narrow embodiment of the lower housing section 118 of the torch housing 210, where the torch housing 210 includes the conical chamber section 252 formed therewithin. In this exemplary embodiment, the lower housing section 118 includes the mounting plate 119 which includes a plurality of mounting apertures, as well as the hollow, conical lower housing body 118a, and a straight length that is the outlet of the microwave plasma torch. A distal diameter (D1) of the lower housing body 118a has a magnitude that is ? or less the magnitude of a height (H1) of the lower housing body 118a.
FIGS. 7C and 7D provide a second embodiment of the lower housing section 118 of the torch housing 210, where the torch housing 210 includes the conical chamber section 252 formed therewithin. In this exemplary embodiment, the lower housing section 118 includes the mounting plate that has a plurality of mounting apertures, as well as the hollow, conical lower housing body 118a, and a straight outlet portion. A height (H2) of the lower housing body 118a has a magnitude that is at least twice as large as a distal diameter (D2) of the lower housing body.
