Limiting rate of inductionless current drive in a tokamak

The rate of current drive by lower hybrid waves in a tokamak is shown to be limited by the heating of the plasma. The corresponding maximum temporal rate of increase of the injected power is found. A deviation from this maximum rate lowers the efficiency at which the energy of rf waves is converted into energy of the magnetic field.
