A comparative study of stellarator and tokamak transport
A comparison of transport in stellarators and tokamaks should reveal the importance of the magnetic field topology for transport. A first extensive comparison was published four years ago and is briefly summarized here. This work is an extension and specifically builds upon the experimental findings collected since then. It concentrates on aspects including the dependences of the energy confinement time on global and local parameters such as magnetic shear, isotopic mass, density and temperature. An interesting related question is whether global effects can be important. An alternative access to anomalous transport is to measure the fluctuation amplitudes of plasma parameters. As background for the evaluation of experimental results, short summaries are given of the differences in the magnetic configurations of stellarators and tokamaks and of the importance they have for theories on turbulent transport.
