In 1997, JET set the record for the closest approach to scientific breakeven. It attained Q = 0.67, producing 16 MW of fusion energy while injecting 24 MW of thermal power to heat the fuel, [26] a record that endured until 2021. [27] [28] This was also the record for greatest fusion power produced. [29] [30] In 1998, JET's engineers developed a ...
This led to the adoption of the tokamak by the majority of fusion research establishments internationally. In 1977, following protracted negotiations, Culham was chosen as the site for the Joint European Torus (JET) tokamak. [3] Construction began in 1978 and was completed on time and on budget, with first plasma in June 1983.
TFTR (Tokamak Fusion Test Reactor) [10] Shut down: 1980–1982: 1982–1997: Princeton: Princeton Plasma Physics Laboratory: 2.4 m / 0.8 m: 5.9 T: 3 MA: Attempted scientific break-even, reached record fusion power of 10.7 MW and temperature of 510 MK: Tokamak de Varennes (TdeV) Shut down? 1983–1997: Montreal: National Research Council Canada ...
The current record of fusion power generated by MCF devices is held by JET. In 1997, JET set the record of 16 megawatts of transient fusion power with a gain factor of Q = 0.62 and 4 megawatts steady state fusion power with Q = 0.18 for 4 seconds. [3] In 2021, JET sustained Q = 0.33 for 5 seconds and produced 59 megajoules of energy, beating ...
The JT-60 tokamak in Japan produced a high performance reversed shear plasma with the equivalent fusion amplification factor of 1.25 - the current world record of Q, fusion energy gain factor. Results of European-based study of heavy ion driven fusion power system (HIDIF, GSI-98-06) incorporates telescoping beams of multiple isotopic species.
JT-60 (short for Japan Torus-60) is a large research tokamak, the flagship of the Japanese National Institute for Quantum Science and Technology's fusion energy directorate. As of 2023 the device is known as JT-60SA and is the largest operational superconducting tokamak in the world, [ 1 ] built and operated jointly by the European Union and ...
[13] The term "tokamak" was coined in 1957 [14] by Igor Golovin, a student of academician Igor Kurchatov.It originally sounded like "tokamag" ("токамаг") — an acronym of the words "toroidal chamber magnetic" ("тороидальная камера магнитная"), but Natan Yavlinsky, the author of the first toroidal system, proposed replacing "-mag" with "-mak" for euphony.

First plasma was obtained on NSTX on Friday, February 12, 1999 at 7:06 p.m. . Magnetic fusion experiments use plasmas composed of one or more hydrogen isotopes.For example, in 1994, PPPL's Tokamak Fusion Test Reactor produced a world-record 10.7 megawatts of fusion power from a plasma composed of equal parts of deuterium and tritium, a fuel mix likely to be used in commercial fusion power ...
