Theory of runaway-current sustainment by lower-hybrid waves
Abstract
A mechanism is proposed whereby high phase velocity lower hybrid waves can interact with lower parallel velocity electrons through nonlinearly excited plasma waves. Significant steady state current is sustained by the RF after the ohmic field is turned off in a Tokamak provided the initial electron distribution is in the runaway regime with density below a critical value.
