Alcator C-Mod is the high-field, high-density divertor tokamak in the world fusion program. Located at the Massachusetts Institute of Technology, it is one of only four divertor tokamaks in the world program capable of plasma currents exceeding one mega-ampere. The central mission of the Alcator program is to carry out compact, high-performance divertor tokamak research to establish the plasma physics and plasma engineering necessary for an ignited tokamak experiment and for attractive fusion reactors.

In the area of transport, C-Mod is making critical tests of theoretically-based interpretations of tokamak transport, at dimensional parameters that are unique, but at dimensionless parameters comparable to those in much larger experiments. Additionally, a major thrust of research on C-Mod is to develop our physics understanding of the advanced tokamak regime.

For all these reasons, C-Mod is well-positioned to provide high quality experimental data to the Center.
