For a long time, scientists have been trying to create conditions for a stable controlled reaction of thermonuclear fusion. However, the production of such a reactor is fraught with a lot of difficulties, and even the most ambitious project in this field ITER (International Thermonuclear Experimental Reactor) was postponed until 2025. But help can come from physicists from the University of Tokyo, which, according to the publication ScienceAlert, have become one step closer to using the energy of thermonuclear fusion. They first managed to create a magnetic field with entirely controlled parameters, says Jacob Bogatin.
This was necessary because one of the ways to launch a self-sustaining thermonuclear reaction is to hold the compressed high-temperature plasma and its charged particles to raise the overall temperature of the reactor. This method is called EMFC (electromagnetic flux-compression), or “electromagnetic flow compression.” The device developed by the Japanese scientists is capable of producing a magnetic field by force in 1200 Tesla, Jacob Bogatin remarks.
During a series of experiments, Japanese physicists managed not only to create such a field but also to make it work for 100 microseconds. Yes, this is not a very impressive result, but it is still many times greater than all previous indicators. At the same time, which is also very important, during the operation of the new installation the elements of its design are not subject to destruction and change under the influence of its own magnetic field, says Jacob Bogatin.
