What is the fusion of magnetic imprisonment?
Magnetic imprisonment is access to nuclear fusion, which includes plasma suspension (ionized gas) in the magnetic field and increases its temperature and pressure on large levels. Nuclear fusion is a type of nuclear energy produced when the atomic cores of the light - hydrogen, deuterium, tritium or helium - are connected at large temperatures and pressures. All light and heat of the sun come from nuclear fusion reactions taking place in its core. The sun may exist at all - the external pressure of the fusion reactions tends to tend to gravitational collapse.
Although humanity has used fission energy - it broke heavy cores - for nuclear energy, the successful fusion power still escapes us. So far, every attempt to generate fusion energy consumes more energy than it produces. Magnetic imprisonment is one of the two popular approaches to nuclear fusion - the second is the fusion of inertial imprisonment, which includes bombing apelive pellet with high -performance lasers. There is currently one project with more billionsDami dollars for every journey-national ignition device in the United States monitors the merger of a remaining imprisonment and an international thermonuclear experimental reactor, an international project, monitors the merger of magnetic imprisonment.
Experiments in magnetic imprisonment began in 1951, when Lyman Spitzer, physicist and astronomer, built a star, a plasma -shaped plasma device. The main breakthrough came in 1968, when Russian scientists introduced tokamak public design, Torus, which would be the design of the most magnetic fusion devices that will come. In 1991, there was another step forward with the construction of the start (small tight ratio of Tokamak) in the UK, spheromak or spherical tokamak. Testing has shown that this device is about three better than most tokamaks to initiate fusion reactions and spheromaks continues to be a continued area of investigation in research.
to be fTeric reaction effective, the center of the tokamac reactor must be heated to temperatures of around 100 million Kelvin. At such high temperatures, particles have huge kinetic energy and are constantly trying to escape. One fusion research compares the challenge of magnetic imprisonment with the challenge of pressing the balloon - if you press hard on one side, just appears on another. When the magnetic imprisonment is fusing, this "jumping" causes the particles of high -temperature particles to collide with the reactor wall and rob metal pieces in a process known as "spraying". These particles absorb energy and reduce the total temperature of limited plasma and make it difficult to achieve the correct temperature.
If the strength of the merger could be managed, it could become an unrivaled source of energy for humanity, but even the most optimistic scientists do not expect commercial energy production before 2030.
