Abstract : This patent discloses an intense, space-charge-neutralized, pulsed ion beam is used to heat a magnetically-confined plasma, such as tokamak plasma, by injecting the ion beam into the plasma along a trajectory that is generally tangential to the confining magnetic field. The intense ion beam is injected into the tokamak before the plasma is fully formed, the remainder of the plasma is fully formed, the remainder of the plasma is formed around the beam, and the beam transfers its energy to the plasma by classical collisions with the electrons and ions of the plasma. Heating of the plasma can be sufficient to produce breakeven or ignition.
