Tokamak - Wikipedia
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]
Magnetic control of tokamak plasmas through deep …
2022年2月16日 · A newly designed control architecture uses deep reinforcement learning to learn to command the coils of a tokamak, and successfully stabilizes a wide variety of fusion plasma configurations.
Tokamak - ITER
The heart of a tokamak is its doughnut-shaped vacuum chamber. Inside, under the influence of extreme heat and pressure, gaseous hydrogen fuel becomes a plasma—a hot, electrically charged gas. In a star as in a fusion device, plasmas provide the environment in which light elements can fuse and yield energy.
DOE Explains...Tokamaks | Department of Energy
A tokamak is a machine that confines a plasma using magnetic fields in a donut shape that scientists call a torus. Fusion energy scientists believe that tokamaks are the leading plasma confinement concept for future fusion power plants.
A high-density and high-confinement tokamak plasma regime …
2024年4月24日 · The tokamak approach, utilizing a toroidal magnetic field configuration to confine a hot plasma, is one of the most promising designs for developing reactors that can exploit nuclear fusion to...
What is a tokamak? - iter.org
3 天之前 · The tokamak is an experimental machine designed to harness the energy of fusion; inside a tokamak, a fusion plasma is created and confined by strong magnetic fields. The energy produced through the fusion of atoms in the plasma is absorbed as heat in the walls of the vessel. Just like a conventional power plant, a fusion power plant will use ...
International tokamak research
3 天之前 · The SST-1 plasma carries all the standard attributes of tokamak plasma in contemporary devices. SST-1 is also the only tokamak in the world with superconducting toroidal field magnets operating in two-phase helium instead of supercritical helium in a cryo-stable manner, thereby demonstrating reduced cold helium consumption.
GS-DeepNet: mastering tokamak plasma equilibria with deep …
2023年9月22日 · A tokamak is a torus-shape vacuum vessel within which the plasma is confined by magnetic fields directed along the long (toroidal) and short (poloidal) ways around the torus.
Accelerating fusion science through learned plasma control
In a paper published today in Nature, we describe how we can successfully control nuclear fusion plasma by building and running controllers on the Variable Configuration Tokamak (TCV) in Lausanne, Switzerland. Using a learning architecture that combines deep RL and a simulated environment, we produced controllers that can both keep the plasma ...
