The Tokamak Fusion Test Reactor (TFTR) was an experimental tokamak built at Princeton Plasma Physics Laboratory (in Princeton, New Jersey) circa 1980. Following on from the PDX (Poloidal Diverter Experiment) and PLT (Princeton Large Torus) devices, it was hoped that TFTR would finally achieve fusion energy break-even. Unfortunately, the TFTR never achieved this goal. However it did produce major advances in confinement time and energy density, which ultimately contributed to the knowledge base necessary to build ITER. TFTR operated from 1982 to 1997.

In 1986 it produced the first 'supershots' which produced many more fusion neutrons.[1]

In 1994 it produced a then world-record 10.7 megawatts of fusion power from a plasma composed of equal parts of deuterium and tritium (exceeded at JET in the UK, which generated 16MW for 22MW input in 1997, which is the current record).

It was followed by the NSTX spherical tokamak.
