Analysis of Inductively Coupled Electrodeless Discharge by Equivalent Circuit

An equivalent circuit model for inductively coupled electrodeless discharge including an excitation coil is introduced. The validity of the model is verified by an experiment using a simulation tube. By comparing the experimental data of applied voltage and current of the excitation coil with calculation by the model, plasma conductivity and induced discharge current in the inductively coupled electrodeless discharge are estimated. First, the distribution shape of plasma conductivity is estimated. Then, plasma conductivity at the axis, σ0, is approximated by the following equation for the employed discharge tube. σ0=0.29i D1.54 S/m, where i D is induced discharge current in A(rms)/m.
