Self-absorption Effects In Experimental Methods Used To Determine Electron Density And Gas Temperature In An Argon Microwave Plasma (SWP) Generated At Atmospheric Pressure

摘要

In this work a procedure was applied to verify that self-absorption does not affect thespectral lines used in the experimental determination of the electron density and the gastemperature in surface wave discharges at atmospheric pressure. Therefore, the values ofelectron density and gas temperature obtained are not perturbed by this phenomenon.
