In October 2023, JET set its final fusion energy record, producing 69.29 megajoules over 6 seconds from only 0.21 mg of D-T fuel. [ 41 ] [ 42 ] In November 2023, a petition asking that JET not be closed was started, with scientists fearing a research time gap and personnel loss between JET's closure and the start of ITER's operations.

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 ...
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 ...
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 Lockheed Martin Compact Fusion Reactor (CFR) was a fusion power project at Lockheed Martin’s Skunk Works. [1] Its high-beta configuration, which implies that the ratio of plasma pressure to magnetic pressure is greater than or equal to 1 (compared to tokamak designs' 0.05), allows a compact design and expedited development.
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 ...
