Mach-Zenhder 간섭계를 이용한 아크방전 중의 전자밀도 측정
Electron density measurment in arc discharge using Mach-Zenhder interferometer
초록
The Laser aided diagnostic method makes it possible to diagnose plasma characteristics which have never been done by other one. The aim of this study is to measure the electron density profile of an arc plasma by Mach-Zenhder interferometer. The two laser beams (He-Ne and Argon Lasers), which are different in wavelength, pass across an arc plasma and meet a change of refractivity which makes fringe shifts. From this effects we could find densities of electron and neutral particle.
