Princeton Tokamak Begins Experiments with Tritium–Deuterium Plasmas
DOI: 10.1063/1.2808357
Tokamak research entered a new and important phase last month. Shortly before midnight on 9 December, the 11‐year‐old Tokamak Fusion Test Reactor at the Princeton Plasma Physics Laboratory was fired for the first time with a 50:50 mixture of deuterium and tritium. That’s the mixture of hydrogen isotopes envisioned for the first generation of fusion reactors, because DT fusion can be harnessed at much lower temperatures than DD or
