Abstract
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, and 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.
Claims8
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.
