Heavy ion fusion - using heavy ions to make electricity

The idea of using nuclear fusion as a source of commercial electrical power has been pursued worldwide since the 1950's. Two approaches, using 'magnetic' and 'inertial' confinement of the reactants, are under study. This paper describes the difference between the two approaches, and discusses in more detail the 'heavy-ion-driven' inertial fusion concept. A multibeam induction linear accelerator would be used to bring ∼100 heavy ion beams to a few GeV. The beams would then heat and compress a target of solid D-T. This approach is unique among fusion concepts in its ability to protect the reaction chamber wall from neutrons and debris. (author)
