The Tokamak Fusion Test Reactor (TFTR) was an experimental tokamak fusion test reactor 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.
