A fluidized reactor system for removing impurities from a gas and an associated process are provided. Thereafter it is determined whether the detected context description is equal to a predetermined context description. A flash emitter emits flash light. In other versions, auxiliary inductances are selectively switched in and out of circuit to alter the frequency of the primary voltage to the transformer. A third harmonic generator is coupled to the second harmonic generator and produces a UV output beam. The stability of present composition is improved, especially, at high temperatures.
