Highest temperature

In 1994, the highest temperature produced in a lab was a plasma temperature of 510 million degrees Celsius (918,000,000 deg F) in the Tokamak Fusion Test Reactor (TFTR) operated at the Princeton Plasma Physics Laboratory of Princeton University. An early record was set there in 1985, when the TFTR was the first tokamak to achieve the reactor temperature of 100 million degrees Celsius. The TFTR (Dec 1982-Apr 1997) was the largest magnetic fusion experiment in the U.S. and was the first such device in the world to studied the confinement and heating of plasmas with 50/50 mixtures of deuterium and tritium - the fuel mixture likely to be used in the commercial fusion power plants of the twenty-first century.
