HEAVY-ION ACCELERATORS FOR INERTIAL FUSION

A short review of alternative solutions to the supply of energy is given, in the framework of today's requirements by society. The inertial-fusion option is shown to have the potential to satisfy these requirements. The recent << renaissance >> of the studies in inertial fusion is noted, but the field should be brought out of its present phase of << experimental stagnation >>. An overview of the pending questions is presented and the need is stressed for projects aiming to reach ignition. In particular an ion-accelerator-driven project is considered to be a necessary next step for an international collaboration.
