Electromagnetic waves with frequencies near the ion cyclotron frequency or its harmonics (ICRF) have been used effectively for heating fusion grade plasmas in magnetic confinement devices, in particular, tokamaks. While the propagation characteristics of such waves in complex magnetic field geometries can be predicted by large codes, to date little experimental information has been available from the core of hot plasmas on the nature of such waves. Of particular importance is the possible conversion of the long wavelength electromagnetic waves (the Fast Magnetosonic Wave) to short wavelength kinetic waves (Bernstein waves) in the presence of multiple ion species. In the Alcator C-Mod tokamak CO-2 laser beam aided Phase Contrast Imaging (PCI) techniques have been used to detect the Fast Wave, and to map out the wave pattern near the mode conversion layer. In these multi-MW RF wave studies at 80 MHz unexpected mode structures have been discovered with mm scale-lengths which are being analyzed by a full wave EM field solver.
