Abstract

"When a microwave signal with a frequency near the electron upper hybrid resonance is applied to a magnetoplasma, it will excite the plasma. The perturbation of plasma can be detected by using Langmuir probes. The particular plasma used in this experiment is an argon discharge type and the density is relatively low (n~10⁸ cm⁻³). The electron temperature is about 7000º K. Because a magnetic field is applied to the plasma, it is necessary to use the probe theory in a magnetic field to calculate the electron number density from the electron temperature. In order to determine the electron upper hybrid frequency, it is necessary, at least, to roughly determine the electron number density of the argon magnetoplasma. By using aplasmograph circuit, electron temperature can be calculated from the transition region of the plasma V-I characteristic curve. Then the electron number density can be calculated from electron temperature. After the electron upper hybrid resonance frequency has been found, the plasma can be perturbed and from the change of probe current, the perturbation of the microwave on electron temperature can be calculated"--Abstract, page ii.
