JET was one of only two tokamak models designed to work with a real deuterium-tritium fuel mix, the other being the US-built TFTR. Both were built with the hope of reaching scientific breakeven where the "fusion energy gain factor" or Q = 1.0. [18] [6] [19] [20] JET achieved its first plasma on 25 June 1983. [14]
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 ...
The Culham Centre for Fusion Energy (CCFE) is the UK's national laboratory for fusion research.It is located at the Culham Science Centre, near Culham, Oxfordshire, and is the site of the Mega Ampere Spherical Tokamak (MAST) and the now closed Joint European Torus (JET) and Small Tight Aspect Ratio Tokamak (START).
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.

The energy put into these particles is thus lost, and it is easy to demonstrate this is much more energy than the resulting fusion reactions can release. [ 19 ] To maintain fusion and produce net energy output, the bulk of the fuel must be raised to high temperatures so its atoms are constantly colliding at high speed; this gives rise to the ...

The only machine currently under construction that is predicted to break this record is the ITER tokamak in France. ITER is not expected to be fully operational until 2034 [9], meaning that Alcator C-Mod's record will hold for more than 15 years unless another new device is constructed before then. [1]
