The propagation of the fast hydromagnetic wave in a cylindrical plasma is studied. A driving signal having a frequency omega /2 pi = 16 Mc is provided by means of an induction coil wrapped around the center of the plasma device. The ion cyclotron frequency ( OMEGA i/2 pi in the plasma is varied by varying the axial magnetic field intensity, and the experimental conditions are adjusted so that always omega > OMEGA i. The phase shift between the applied signal and the plasma excitation signal is measured as a function of the axial distance from the exciting coil. The experimental results are compared with the predictions of the dispersion relations for omega / OMEGA i = 3.3 and 12.
