SAWTOOTH BEHAVIOUR IN LOWER HYBRID HEATED FT DISCHARGES
The increase of sawtooth repetition time is in agreement with an increase of electrical conductivity. This effect is more important when waves travelling in the electron drift direction are injected into the plasma with respect to the case when a symmetric spectrum is utilized. The increase of the time delay for the propagation of the heat pulse has to be ascribed to a reduction of the electron thermal conductivity. These results are in good agreement with a model of the sawtooth dynamics and with the energy balance results.
