Abstract

In a rotating magnetized plasma cylinder with shear, cross field current can arise from inertial mechanisms and from the cross field viscosity. Considering these mechanisms, it is possible to calculate the irreducible radial current draw in a cylindrical geometry as a function of the rotation frequency. The resulting expressions raise novel possibilities for tailoring the electric field profile by controlling the density and temperature profiles of a plasma.
