Description

Electron heat transport in the Wendelstein stellarator and the RTP tokamak is determined by heat pulse propagation and power balance analysis and compared. In both machines heat pulses are generated with modulated ECH, the sawtooth instability gives additional transport data in RTP. The question is whether or not a model exists which describes electron heat transport and power degradation of confinement in both RTP and W7-AS as a function of local variables only. A preliminary conclusion is that χe does not explicitly depend on Te and ∇Te in RTP and W7-AS and that a local description of power degradation is not feasible in W7-AS. (author) 12 refs., 2 figs
