In one embodiment, as shown in FIG, 2F, the gas input/output ports 210, 212 may also serve as plasma ignition electrodes. For example, the system 100 may include one or more electrical feedthroughs 224. The one or more electrical feedthroughs 224 may serve to insulate metal gas input/output tubes 210, 212. Further, the gas input/output tubes 210, 212 may be electrically coupled to a high-voltage source 225 for delivering electrical energy to the gas 107 for igniting the plasma 106. In addition, the system 100 may include one or more electrical insulating sections 220 for insulating the rest of the gas circulation system 209 from the electrified gas input/output tubes 210, 212.
In another embodiment, the reflector assembly 202 is a multi-component reflector assembly. In this regard, the elliptical shell of the assembly 202 may be formed from two or more components. For example, as shown in
