Abstract

Recent results from the Alfven wave heating experiments on the TCA tokamak have confirmed very strong sawtooth activity on the peak electron temperature, with the delivered rf power roughly equal to the Ohmic power. This could be interpreted as being due to a very peaked rf power deposition profile, in which case it would not correspond to the dissipation of all the Alfven wave energy locally at the resonance layers. It is possible that the mechanisms responsible might be the conversion to, and subsequent dissipation of, the kinetic Alfven wave.
