The Compact Ignition Tokamak (CIT) was a plasma physics experiment that was designed but not built. It was designed by an inter-organizational team in the US led by Princeton Plasma Physics Laboratory. The experiment was designed to achieve a self-sustaining thermonuclear fusion reaction in a tokamak with the minimum possible budget. [1]
A tokamak (/ ˈ t oʊ k ə m æ k /; Russian: токамáк) is a device which uses a powerful magnetic field generated by external magnets to confine plasma in the shape of an axially symmetrical torus. [1] The tokamak is one of several types of magnetic confinement devices being developed to produce controlled thermonuclear fusion power.
Started in 1977 by Prof. Bruno Coppi at MIT, Ignitor based on the 1970s Alcator machine at MIT which pioneered the high magnetic field approach to plasma magnetic confinement, continued with the Alcator C/C-Mod at MIT and the FT/FTU series of experiments. [1]
Fusion ignition is the point at which a nuclear fusion reaction becomes self-sustaining. This occurs when the energy being given off by the reaction heats the fuel mass more rapidly than it cools. In other words, fusion ignition is the point at which the increasing self-heating of the nuclear fusion removes the need for external heating. [1]
The National Ignition Facility (NIF) is a laser-based inertial confinement fusion (ICF) research device, located at Lawrence Livermore National Laboratory in Livermore, California, United States. NIF's mission is to achieve fusion ignition with high energy gain .
A typical plasma in the MAST spherical tokamak machine at the Culham Centre for Fusion Energy in the UK.. Magnetic confinement fusion (MCF) is an approach to generate thermonuclear fusion power that uses magnetic fields to confine fusion fuel in the form of a plasma.

The first, the Compact Ignition Tokamak, which was intended to be a relatively low cost device to heat a plasma to conditions such that the energy released by its nuclear fusion reactions is sufficient to keep the process going, eventually evolved into the Tokamak Physics Experiment, which was not intended to reach ignition, but rather to ...
