The Divertor Tokamak Test (DTT) is a planned superconducting tokamak currently under construction in Frascati, Italy. [1] It is set to be operated by the Italian government-sponsored research and development agency, ENEA, and will serve as a testbed for the construction of a DEMOnstration Power Plant. [2]
Interior of Alcator C-Mod showing the lower divertor channel at the bottom of the torus Divertor design for K-DEMO, a planned future tokamak experiment Divertor of COMPASS. In magnetic confinement fusion, a divertor is a magnetic field configuration which diverts the heat and particles escaped from the magnetically confined plasma to dedicated plasma-facing components, thus spatially ...
ITER (initially the International Thermonuclear Experimental Reactor, iter meaning "the way" or "the path" in Latin [2] [3] [4]) is an international nuclear fusion research and engineering megaproject aimed at creating energy through a fusion process similar to that of the Sun. It is being built next to the Cadarache facility in southern France.
Some scenarios emphasized "fusion nuclear science facilities" as a step beyond ITER. [157] [158] However, the economic obstacles to tokamak-based fusion power remain immense, requiring investment to fund prototype tokamak reactors [159] and development of new supply chains, [160] a problem which will affect any kind of fusion reactor. [161]
To deliver power to the fusion plasma in ITER, two heating neutral beam injectors will be installed. They are designed to provide the power of 17 MW each, through the 23 m beamlines, up to the four-meter diameter container: in order to deposit sufficient heating power in the plasma core instead of the plasma edges, the beam particle energy shall be about 1 MeV, thus increasing the neutral beam ...
[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]
In order to stop this boundary layer problem from happening, a splitter plate may be used to separate the boundary layer from the fast-moving free airflow and divert it away from the engine intake. Many splitter plates have a series of holes drilled into the surface closer to the engine side of the intake. [ 1 ]
One researcher has described the magnetic confinement problem in simple terms, likening it to squeezing a balloon – the air will always attempt to "pop out" somewhere else. Turbulence in the plasma has proven to be a major problem, causing the plasma to escape the confinement area, and potentially touch the walls of the container.
