Abstract

The results of experiments performed to probe the transport properties of Rijnhuizen Tokamak Project (RTP) are presented. To provide a localized source of electron temperature perturbations that propagate across the barriers, modulated electron cyclotron heating (ECH) was used. In RTP plasmas with dominant ECH, electron heat transport barriers behave nondiffusively when probed by heat waves from modulated ECH. The results suggests the existence of heat pinch layers pumping heat inward against the electron temperature gradient.
