Internal view of the JET tokamak superimposed with an image of a plasma taken with a visible spectrum video camera. JET has a major radius of 3 metres, and the D-shaped vacuum chamber is 2.5 metres wide and 4.2 metres high. [45] The total plasma volume within it is 100 cubic metres, about 100 times larger than the largest machine in production ...
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).

In 2021, JET sustained Q = 0.33 for 5 seconds and produced 59 megajoules of energy, beating the record 21.7 megajoules released in 1997 over around 4 seconds. [ 4 ] One of the challenges of MCF research is the development and extrapolation of plasma scenarios to power plant conditions, where good fusion performance and energy confinement must ...
The current record for highest Q in a tokamak (as recorded during actual D-T fusion) was set by JET at Q = 0.67 in 1997. The record for Q ext (the theoretical Q value of D-T fusion as extrapolated from D-D results) in a tokamak is held by JT-60, with Q ext = 1.25, slightly besting JET's earlier Q ext = 1.14.
The design was based on Tokamak Physics Experiment, which was based on Compact Ignition Tokamak design – See Robert J. Goldston. 1995 – Started Project KSTAR; 1997 – JET of EU emits 17 MW energy from itself. 1998 – JT-60U went beyond energy junction successfully and acknowledged the possibility of commercialization of nuclear fusion.
Tokamak Energy is a fusion power company based near Oxford in the United Kingdom, [1] established in 2009. [2] The company is pursuing the global deployment of commercial fusion energy in the 2030s through the combined development of spherical tokamaks with high-temperature superconducting (HTS) magnets. It is also developing HTS magnet ...
