Heavy Ion Accelerators for Inertial Fusion

Heavy ion beams make a good driver for inertial fusion. Two types of accelerator are promising for delivering the requisit high current beams - the rf linac/storage ring system pursued at the Argonne National Laboratory and the induction linac scheme developed at the Lawrence Berkeley Laboratory. The progress at these laboratories is, however, regrettably slow due to lack of funding. The general requirements on the driver for heavy ion fusion are reviewed and the status of various R&D efforts is discussed.
