NDCX-II, the second generation Neutralized Drift Compression Experiment, is an unusual special-purpose particle accelerator designed to produce a high-quality, dense ion beam that can be used to inform and guide the design of major components for heavy-ion fusion energy production. The Berkeley Lab Engineering Division designed and fabricated the high voltage injectors and accelerator structures and conducted the electrostatic simulation and analysis for the NDCX-II project.
