ABSTRACT:
An intense, space-charge-neutralized, pulsed ion beam is used to heat a metically-confined plasma, such as a tokamak plasma, by injecting the ion beam into the plasma along a trajectory that is generally tangential to the confining magnetic field. The ion beam inductively generates a plasma return current so that no net current is produced. As the ion beam drifts in the plasma, the confining magnetic field is transformed into one which can trap the ion beam at the center of the plasma. Once the ion beam is trapped, the plasma return current is cancelled by transformer action to produce a net current which is carried by the ion beam alone. 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 a breakeven condition or ignition.
