Excitation of Fast Waves near the Mean Gyrofrequency
Published Web Locationhttps://doi.org/10.1103/physrevlett.57.2276
Fast waves with frequencies near the mean gyrofrequency [̂Ä(cice)12] were excited in a toroidal, magnetized plasma. Experimental measurements were made of wavelengths and phase velocities perpendicular to the toroidal magnetic field, and wave energy trajectories in the plasma, with varying wave frequency, plasma density, and magnetic field values. Experimental results agree with predictions from the cold-plasma dispersion relation. © 1986 The American Physical Society.
