| dc.description | Radial electron thermal and particle diffusivities have been measured using transient methods yielding chi <sub>e</sub> and D<sub>e</sub> simultaneously in the same spatial region in the plasma interior. Three methods have been applied, analysis of inward propagation of temperature and density perturbations caused by injection of a small pellet into the plasma, the outward propagation of electron temperature and density pulses caused by sawteeth, and thirdly time-dependent transport analysis applied to non-stationary plasmas. In Ohmically heated deuterium plasmas, limited by the outer carbon belt-limiters, the authors deduce chi <sub>e</sub>=2.9+or-0.4 m<sup>2</sup> s<sup>-1</sup> and D<sub>e</sub>=0.4+or-0.2 m<sup>2</sup> s<sup>-1</sup>, giving chi <sub>e</sub>/D<sub>e</sub>=7.2+or-3. The large value of chi <sub>e</sub>/D<sub>e</sub> would seem to exclude E*B convection as a dominant mechanism in the observed radial thermal transport in JET. |
