Investigation of the electron heat conductivity as a function of injected power, plasma current and density at TEXTOR
By having an aperture in the neutral beam, it was possible to study the influence of various plasma parameters on the electron heat conductivity coefficient at TEXTOR. Experiments show a scaling with plasma current, toroidal magnetic field and Z(eff), but no indication of density dependence. Above a 400 eV threshold a strong increase was found in the transport coefficient, possibly due to isolation of the magnetic field structure. Where the electrons are subject to a free streaming rather than a diffusive process, this results in a decrease of the heat pulse propagation time.
