INTRODUCTION
The Neutralized Drift Compression Experiment (NDCX) is being constructed at the Lawrence Berkeley National Laboratory. NDCX will help develop novel, still unexplored beam manipulation techniques in order to establish the physics limits on compression of heavy ion beams for creating high energy density matter and fusion ignition conditions [1]. A critical early component being developed in this series of experiments is the Accel-Decel Injector which will enable a dramatic increase in ion beam line charge density after extraction from the ion source.
