Thirty years ago at 3:06 am December 24, 1982, TFTR produced its
first plasma, thus completing the official construction project after
seven years of construction. TFTR went on to operate for 15 years
and increased the fusion power gain by a factor of 1 million over the
value when it was designed in 1975 to a value of 0.3 in 1995. Other
TFTR milestones included: the first tokamak to use power plant DT
fuel, first measurements of alpha-heating by the fusion reaction,
record fusion fuel temperatures of 45 keV (500 million° C), and
fusion power exceeding 10 million watts. Using advanced
diagnostics, TFTR made numerous contributions to the understanding of
plasma physics at the frontier of fusion plasma physics. The US fusion
budget was cut by 35% in 1996 forcing the termination of TFTR
experiments on April 4, 1997. The total cost of the TFTR Project
(design, construction, operation and decommissioning) was $1.6 B.
