Abstract : The n = ! 1, E mode of hydromagnetic wave propagation has been studied in a cylindrical plasma waveguide. Excitation at 1.0, 2.3, and 3.0 megacycles per second was achieved by means of a circular current-carrying loop immersed in the plasma. Magnetic probes, distributed along the length of the waveguide and capable of insertionALONG A RADIUS, WERE USED TO DETERMINE THE RADIAL DEPENDENCE AND DIRECTION OF THE SIGNAL FIELDS AND, HENCE, THE NATURE OF THE PROPAGATING MODE. These probes were also used to detect the propagation of the waves. Measurement of wave velocity was interpreted to yield the ion density in the plasma, and, furthermore, measurement of wave velocity at different intervals after plasma preparation was interpreted to yield the ion density decay rate. Experiments were performed to detect the rotation of the plane of polarization of the signal fields. (Author)
