Pfirsch-Schlüter current (PSC) is an inherent property of a finite pressuretoroidal plasma equilibrium in tokamaks and stellarators. However, it has been pointedout (V.D. Pustovitov, Nucl. Fusion 36 (1996) 583) that the PSC in a conventionalstellarator could be suppressed completely by adjusting the external vertical magneticfield so that it satisfies the condition that the quantity characterizing theinhomogeneity of the magnetic field strength on a flux surface is a flux function.In this article an example is presented of such an l = 3 stellarator equilibrium.Complete suppression of PSC in a finite beta plasma is shown numerically by using thefixed boundary version of the VMEC code. The calculated equilibrium is alsoanalysed from the viewpoint of the Boozer magnetic spectrum. It is shown that a reductionof the poloidal inhomogeneity of the magnetic field strength is essential for reducingthe PSC.
