Current sustaining by RF travelling field in a collisional toroidal plasma
Abstract
Phase velocity and filling gas pressure or electron collision frequency were parameters used in an investigation of current generation by the RF traveling field in a collisional toroidal plasma. On the basis of the fluid model used, an electromotive force, which acts as a current driving electric field, is introduced. In a low magnetic field, the current is proportional to the plasma conductivity. The electromotive force is proportional to the absorbed RF power and inversely proportional to the plasma density and the phase velocity of the traveling field.
