1. Apparatus for heating a plasma, the plasma being confined in an apparatus of the type wherein the plasma is confined in a vacuum chamber by a magnetic field, comprising:

  • means for producing a space-charge-neutralized, pulsed, ion beam;

    means for directing the ion beam into the magnetic field before the plasma is fully formed; and

    means for forming the remainder of the plasma around the beam,the beam transferring its energy to the plasma by classical collisions with the electrons and ions of the plasma.
