Microwave Device on the Basis of a Barrel Resonator for Determining the Average Density and the Density Profile in Plasma Formations
Keywords:microwave resonator, plasma, radial distribution function, resonance frequency, plasma density
A microwave resonator device for measuring the plasma density is described. A method is proposed for determining the radial distribution function of the plasma density by measuring a shift of resonance frequencies for two oscillation modes. According to experimental results, the device is suitable for measuring the plasma density in the range 109 –1011 cm−3.
