For decades, although nuclear fusion has always been the direction of clean energy development, it has been a difficult problem to overcome. If a commercially viable fusion reactor can become a reality, it will soon become the mainstream energy source in the future, which is also the significance of MIT’s research and development of super magnets. Nuclear fusion only occurs at extremely high temperatures-the plasma must reach a certain temperature to melt the materials used to build the reactor.

The scientific community has been A solution was proposed to control the plasma without touching any objects. A strong magnetic field can do this, creating an artificial “container” in which nuclear fusion can occur. MIT researchers hope to arrange their powerful new magnets into the tokamak reactor by 2025, and the result will be net positive nuclear fusion.

In fact, the real breakthrough work is not Nuclear fusion itself. Artificial fusion reactions have occurred before, but so far, they have always consumed more energy than they generate (maintaining these magnetic fields to contain the plasma requires a lot of energy). By improving the magnet, the MIT research team hopes to become the first reactor to eventually produce more energy than it consumes. This technology ultimately uses traditional plasma physics, tokamak design and engineering to create a new magnet technology.

According to reports, not long ago, China’s all-superconducting Tokamak nuclear fusion experimental device “Oriental Super Ring” broke the world record: in its 98958th discharge, it successfully achieved a repeatable 120 million The plasma runs for 101 seconds and 160 million degrees Celsius for 20 seconds, five times the original record of 100 million degrees Celsius for 20 seconds.

It indicates that China will continue to lead the international frontier in the field of steady-state high-parameter magnetic confinement fusion research.

In reality, China really has “artificial suns”, and there are two: one is in the Hefei Institute of Material Science of the Chinese Academy of Sciences on the “Science Island” in the western suburbs of Hefei, Anhui. It is the all-superconducting Tokamak nuclear fusion experimental device (EAST), which is known as the “Eastern Super Ring”; the other is the China Circulator No. 2 M Device (HL -2M).
