Summary

Description

Alcator C-Mod at the Massachusetts Institute of Technology is operated as a DOE national user facility. Alcator C-Mod is a unique, compact tokamak facility that uses intense magnetic fields to confine high-temperature, high-density plasmas in a small volume. One of its unique features are the metal (molybdenum) walls to accommodate high power densities. Alcator C-Mod has made significant contributions to the world fusion program in the areas of plasma heating, stability, and confinement of high field tokamaks, which are important integrating issues related to ignition of burning of fusion plasma. DOE’s Office of Science, Fusion Energy Sciences program, is a significant contributor to the operation of this facility.
