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 ...
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 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 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]
California has hit a new renewables record after exceeding 100 per cent of grid demand with clean energy sources for 30 of the past 38 days. New data from California Independent System Operator ...
A tokamak (/ ˈ t oʊ k ə m æ k /; Russian: токамáк) is a device which uses a powerful magnetic field generated by external magnets to confine plasma in the shape of an axially symmetrical torus. [1] The tokamak is one of several types of magnetic confinement devices being developed to produce controlled thermonuclear fusion power.
