Overview of the Heavy Ion Fusion program

Abstract

The world Heavy Ion fusion (HIF) Program for inertial fusion energy is looking toward the development and commissioning of several new experiments. Recent and planned upgrades of the facilities at GSI, in Russia, and in Japan greatly enhance the ability to study energy deposition in hot dense matter. Worldwide target design developments have focused on non-ignition targets for nearterm experiments and designs which, while lowering the energy required for ignition, tighten accelerator requirements. The U.S. program is transitioning between scaled beam dynamics experiments and high current experiements with power-plant-driver-scale beams. Current effort is aimed at prepations for the next-step large induction linac accelerating multiple beams to a few hundred MeV, then focusing to deliver tens of kilojoules to a target. The goal is to study hevay ion energy deposition, and to test all of the components and physics needed for an engineering test of a power plant driver and target chamber. This paper will include an overview of the Heavy Ion Fusion program abroad and a more in-depth view of the progress and plans of the U.S. program.
