PLUME CONTROLLABLE SURFACE-DISCHARGED LOW TEMPERATURE ATMOSPHERIC PRESSURE PLASMA JET

摘要

It is an object of the present invention to provide a plasma jet source controlled in accordance with a desired shape of a plasma discharge flame discharged from a plasma jet source. In the present invention, the cylindrical internal electrode is disposed inside the cylindrical dielectric body, the cylindrical external electrode is disposed outside the dielectric body, and the difference in distance l ₁ between the end portion of the internal electrode and the dielectric end portion and the difference in distance between the dielectric end portion and the external electrode end portion l ₂ And the length and shape of the discharge voltage and the jet discharge flame were controlled by controlling the shape of the end portion of the external electrode.
