Diagnostics of TP-D Plasma by CO₂ Laser (II)

Abstract

By using 10.6 μm infrared CO₂ laser radiation, measurement of steady TP-D, plasma has been carried out with inter ferometry and scatitering method. Electron density of TP-D plasma was normalized by Rayleigh scattering of pure air as a measuring standard. Measured electron density by interferometry and scattering method as a function of discharge current shows fairly good agreement.
