Patent ID: 8464695

Claim:
A plasma equipment comprising: a microwave oscillator for generating a predetermined microwave band; a microwave resonant cavity for allowing the predetermined microwave band to resonate; microwave radiation means for radiating the microwave into the microwave resonant cavity, wherein the microwave radiation means is a microwave radiation antenna having the shape and the size so as to form a strong electric field of the microwave in a plasma generation field formed by the microwave; plasma ignition means that makes partial discharge in gas in the microwave resonant cavity and then induces plasma in the gas; and control means for controlling the microwave radiation means and the plasma ignition means and a measurement unit for measuring the generation amount or emission intensity of OH radicals and O.sub.3 generated by plasma generation, wherein the microwave radiation means and/or the plasma ignition means process a result of the measurement unit in real time so as to provide the resultant to the control means.
