Bending Experiments with a Space Charge Dominated Heavy Ion Beam
Abstract
High brightness heavy ion beams are considered to be the leading driver candidate for an Inertial Fusion Energy reactor. Since total accelerator length has a strong influence on cost, the Heavy Ion Fusion groups at LLNL and LBNL have been considering the potential advantages and practical implementation of a recirculating induction accelerator. To address the critical scientific and technical challenges of a recirculating space charge dominated heavy ion beam, we have begun to develop the elements of a scaled "small recirculator" at LLNL. An operating recirculator must demonstrate full beam control including multi-lap operation, beam insertion/extraction, acceleration and pulse compression (current amplification). Experiments are currently operational through 90 degrees of bend. This paper will summarize the recirculator specifications and report the latest beam characterization measurements from both 45 and 90 degree bend experiments. Progress on beam diagnostics developments will also be presented.
