Exemples d’utilisation de TOKAMAK dans une phrase

• The tokamak is one of several types of magnetic confinement devices being developed to produce controlled thermonuclear fusion power.
• It is known for the development of the stellarator and tokamak designs, along with numerous fundamental advances in plasma physics and the exploration of many other plasma confinement concepts.
• He also predicted the quasi-particle of sound: the phonon; and in 1951, together with Andrei Sakharov, proposed the Tokamak system.
• Their 1969 report confirmed the Soviet results, resulting in a "veritable stampede" of tokamak construction around the world.
• Introduced in Firestorm Volume 2, this included Black Bison, Plastique, 2000 Committee, Hyena, the Assassination Bureau, Enforcer, Mindboggler, Breathtaker, Pozhar, Sand Demon, Shadowstorm, Shango, Slipknot, Stalnoivolk, Tokamak, Weasel, and Zuggernaut.
• As of 2023 the device is known as JT-60SA and is the largest operational superconducting tokamak in the world, built and operated jointly by the European Union and Japan in Naka, Ibaraki Prefecture.
• A mechanism for magnetically limiting a plasma, and hence for controlling the nuclear fusion in a tokamak; see divertor.
• The ITER tokamak experiment under construction, which aims to demonstrate scientific breakeven, will be the world's largest MCF device.
• The mainline confinement concepts of tokamak and stellarator do this in a toroidal chamber, which allows a great deal of control over the magnetic configuration, but requires a very complex construction.
• Toroidal machines can be axially symmetric, like the tokamak and the reversed field pinch (RFP), or asymmetric, like the stellarator.
• A spherical tokamak is shaped more like a cored apple than the conventional, doughnut-shaped toroidal design used by experiments such as ITER.
• Other nuclear installations at Cadarache include the Tore Supra tokamak – a predecessor to ITER – and the Jules Horowitz Reactor, a 100-megawatt research reactor which is planned to begin operation in 2020.
• The START team began the Mega Ampere Spherical Tokamak Experiment or MAST in 1999 which operated in the Culham Science Centre, UK until 2013.
• In a tokamak the toroidal field is much stronger than the poloidal field, but in an RFP it's just the opposite.
• WEST, Tungsten (W) Environment in Steady-state Tokamak, the name for the refitted Tore Supra tokamak reactor in Cadarache, France.
• This equation is a two-dimensional, nonlinear, elliptic partial differential equation obtained from the reduction of the ideal MHD equations to two dimensions, often for the case of toroidal axisymmetry (the case relevant in a tokamak).
• The 3 October 2019 UK Atomic Energy announcement of its Spherical Tokamak for Energy Production (STEP) grid-connected reactor for 2040 suggests a combined DEMO/PROTO phase machine apparently to be designed to leapfrog the ITER timetable.
• The program is focusing on R&D for pursuing steady-state advanced tokamak operation and supporting design and operation of the ITER experiment now under construction in France.
• CFS aims to build a fusion reactor based on tokamak technology, much more compact and cheaper compared to other existing projects such as the international ITER.
• Alcator A was powered by the Bitter Laboratory's 32 MW DC motor-generators and was the first tokamak in the world to use an air-core transformer for ohmic current drive and heating.
