AN EXPERIMENTAL STUDY OF HELICON WAVE PROPAGATION IN A GASEOUS PLASMA

The results of an experimental study of helicon wave propagation in a partially ionized cylindrical plasma are reported. Conditions were chosen so that the phase velocity of the wave was independent of both the electron and ion mass. The phase velocity, the attenuation and the structure of the plasma magnetic fields are compared with the theoretical treatment of Klozenberg, McNamara and Thonemann in 1964. The agreement is satisfactory. In particular, evidence is presented which supports the anomalously high attenuation due to surface currents which the above theory predicts.
