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 can be 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.Keywords
