Physicists have found a way to control the energy of the stars
Physicists at the Massachusetts Institute of Technology and Commonwealth Fusion Systems have announced their readiness to create a working thermonuclear reactor in the next 15 years. It will carry out thermonuclear fusion, similar to that which takes place in the bowels of stars. For this purpose, scientists use superconducting magnets made of yttrium-barium-copper oxide (YBCO). This is written by Popular Mechanics.
The new technology will be tested during the Sparc experiment, for which a compact tokamak, a toroidal chamber for magnetic confinement of super-hot plasma, will be manufactured. It is planned that during the test the thermonuclear reactor will be used so far to obtain a hundred megawatts of thermal energy. If the experiment is successful, scientists will create a larger reactor that generates 200 megawatts.
YBCO is a high-temperature superconductor that operates at a temperature of 77 kelvin (-196.15 degrees Celsius). Most superconductors function at temperatures close to absolute zero (-273 degrees Celsius).
From this material it is possible to produce powerful magnets that are capable of generating a magnetic field of record strength. For example, a YBCO magnet created by the National High Magnetic Field Laboratory creates a field strength of 32 references. In addition, a high-temperature superconductor makes it possible to make sufficiently powerful magnets of relatively small dimensions.
In December 2017 it was reported that the international thermonuclear experimental reactor ITER (International Thermonuclear Experimental Reactor, ITER) was built in half. According to Bernardo Bigot, the project's general director, the installation is planned to be launched in 2025.
