軸対称アークプラズマの光学的直径とピーク分光強度の新しい実時間測定法 A Novel Real Time Measurement System for the Optical Diameter and the Peak Spectral Intensity of the Axially Symmetric Arc Plasmas
This paper describes a simple method for the real time measurement of the optical diameter and the spa-tial peak spectral intensity of the axially symmetric arc plasmas. The method only uses the integrated radia-tion intensities across the plasma column and along the central line of plasma cross section, which are meas-ured by a 2-channel programmable digital storage oscilloscope to obtain continuously the temporal variation of the optical diameter and the spatial peak spectral intensity of the plasmas.<BR>This method was applied to a Hg arc plasma and it was found out that the optical diameter had no tem-poral variation even if the discharge current was varied.
