HEATING AND TOKAMAK CURRENT MAINTENANCE BY INJECTION OF INTENSE PULSED ION BEAMS

Plasma beams can now be efficiently produced containing several hundred kilojoules of 1 MeV ions. If such beams can be injected into a magnetically-confined toroidal system, present day tokamaks may have good enough confinement to achieve ignition. This paper describes three possible ways of injecting such beams, and presents simulations of the results of such injection.
