Description
The global energy confinement time τE in Wendelstein 7-AS scales with electron density, heating power, magnetic field and minor radius. The scaling deviates from that found in tokamaks, where a scaling of τE with plasma current is observed. If one expresses the current scaling in terms of toroidal magnetic field, the tokamak and stellarator scaling laws become similar. In order to explore the intrinsic mechanism, giving rise to current scaling, the ι(=1/q) scaling of τE is studied in more detail in the currentless stellarator W7-AS. (orig.)
