The neutral beam accelerator at the MIT Plasma Science and Fusion Center’s Alcator C-Mod tokamak. The laboratory, centered around the tokamak, or magnetically confined nuclear fusion device, faces significant cuts under the 2013 presidential budget request. The accelerator fires neutral particles into the plasma, resulting in an X-ray emission that can be used to visualize the plasma within and study its behavior.
