Already for a long time scientists are trying to create conditions for implementing a sustainable controlled thermonuclear fusion reaction. However, the production of such a reactor may cause many difficulties and even the most ambitious project to date in this area, the ITER (International Thermonuclear Experimental Reactor) has been postponed to 2025. But help can come from physicists from the University of Tokyo, which, according to ScienceAlert, are one step closer to using fusion energy. The first time they were able to create a magnetic field with fully controllable parameters.
This was necessary because one of the ways to start self-sustaining fusion reaction is to hold the compressed high-temperature plasma and its charged particles with the aim of raising the overall temperature of the reactor. This method is called EMFC (electromagnetic flux-compression), or “electromagnetic compression”. Japanese scientists developed a device capable of producing a magnetic field strength in Tesla 1200. During a series of experiments by Japanese physicists have managed to not only create such a field, but to force him to work for 100 microseconds. Yes, it’s not a very impressive result, but he still many times greater than all previous levels. That is also very important during the new installation the elements of its construction are not subject to destruction and change under the influence of its own magnetic field. As the developers of the technology from the University of Tokyo,
“You understand, created a new device, the magnetic field is more than 120000 times stronger than the field produced by conventional magnets on the fridge. However, his characteristics and duration as close as possible to the minimum magnetic field characteristics necessary for conducting stable nuclear fusion reactions of. All this makes us one step closer to the moment when we will enjoy a virtually inexhaustible source of energy.”
