Abstract

In biasing experiments the externally imposed current is lowered by the additional electron losses caused by magnetic field perturbation and an increase in the plasma potential. The radial electric field and rotation profiles change accordingly. As a consequence, edge magnetic field perturbations in biasing experiments will result in lower ExB shearing rates, which can be recovered only to some extent by operating at higher electrode voltages.
