Columbia Non-Neutral Torus (CNT)


This is the homepage for the Columbia Non-Neutral Torus experiment.

The Columbia Non-neutral Torus (CNT) is a small stellarator at the Columbia Plasma Physics Laboratory (Columbia University) designed to conduct the first investigation of non-neutral plasmas confined on magnetic surfaces. The experiment, which started operation in November 2004, is funded by the National Science Foundation and the United States Department of Energy in the form of a CAREER award. It was previously funded by a Plasma Physics Junior Faculty Development Award. In addition, it is supported by funds and facilities provided by Columbia University and the Princeton Plasma Physics Off-site University Support program. The theory behind the experiment is funded by an NSF grant through the NSF-DOE partnership in basic plasma science.
