According to reports, the International Thermonuclear Experimental Reactor aims to develop a controlled nuclear fusion technology to realize the dream of "artificial sun", which is of great significance to human beings and can solve the energy problems that plague scientists. At present, the artificial magnetic coil of the international thermonuclear experimental reactor has been put in place, taking an important step!
The artificial magnetic coil is one of the most important components received by the International Thermonuclear Experimental Reactor. It weighs 30,000 pounds and is about 13 tons. The huge copper cable is almost 1 kilometer long and is wound into a structure with a diameter of about 4 meters.
The magnetic coils used in the International Thermonuclear Experimental Reactor are not made of superconducting materials, but will eventually be replaced by more expensive materials. Once the superconducting materials are in place, the International Thermonuclear Experimental Reactor will be tested. The basic principle of fusion reaction is basically the same as that of the solar energy generation. Artificially creating nuclear fusion reaction requires starting energy less than output energy, so that we can get energy from it, but one of the biggest obstacles affecting nuclear fusion so far is magnetic field problem. It is necessary to create a configuration with better strength and fineness so as to constrain the fluid therein, otherwise our existing materials cannot withstand such a high temperature environment.
The magnetic induction is measured by a unit called Tesla. The magnetic field of the large Hadron collider accelerates the magnet at about 8 Tesla. The magnetic field used by the International Thermonuclear Experimental Reactor will reach 13.5 Tesla. Such a powerful magnetic field is generally It is also used in the field of magnetic levitation, but the standards used are obviously not as strict as the international thermonuclear experimental reactor. Scientists use magnetic fields to constrain the behavior of high-temperature plasma torus, and surround the coils to distribute the magnetic field evenly. These high-temperature substances participate in the nuclear fusion reaction under the constraints of the magnetic field. Such super machines are also called tokamaks, relying on magnetic fields. To confine the fusion material and the annular container in which the reaction proceeds.
At present, there are not many countries in the world that can manufacture tokamak devices. The United States, Japan and Europe are in a leading position in this respect. China has also built a superconducting tokamak device to verify the feasibility of using plutonium for nuclear fusion. Nuclear fusion devices can be successfully developed, and the world's energy problems can be largely alleviated. In fact, nuclear fusion is the most common form of energy production in the universe. Without controllable nuclear fusion technology, it cannot be called a smart civilization.
