Ray tracing analysis of LH (lower hybrid) fast waves in CCT (Continuous Current Tokamak)

Lower hybrid fast wave field profiles have been measured in the CCT tokamak. These field maps exhibit characteristics of large n/sub parallel/ wave components, with n/sub perpendicular//n/sub parallel/ approx. = 1, and the wave energy appears to be heavily damped in the toroidal direction. We use a 3-D toroidal ray tracing code to study this wave behavior. The spectral filtering of the fast wave can be partially attributed to mode conversion to the slow wave for the low n/sub parallel/ components. In most parameter regimes, subsequent strong absorption of the converted slow wave via electron Landau and higher harmonic ion damping results.
