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 ...
The project is given the name Tokamak Fusion Test Reactor (TFTR). The Kurchatov Institute builds the TO-2, the first tokamak with a divertor, using a toroidal configuration which would soon be superseded by poloidal divertors. [27] 1977. The 20 beam Shiva laser at LLNL is completed, capable of delivering 10.2 kilojoules of infrared energy on ...
[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. [15]
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 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 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 ...
In 1991 JET's Preliminary Tritium Experiment achieved the world's first controlled release of fusion power. [70] In 1992, Physics Today published Robert McCory's outline of the current state of ICF, advocating for a national ignition facility. [71] This was followed by a review article from John Lindl in 1995, [72] making the same
A record 59 megajoules of sustained fusion energy was demonstrated by scientists and engineers working on JET in December 2021. In JET’s final deuterium-tritium experiments , high fusion power was consistently produced for 5 seconds, resulting in a ground-breaking record of 69 megajoules using a mere 0.2 milligrams of fuel. JET has now ceased ...
