Kyrgyz scientist Askar Abdukadyrov has published a study that may be linked to solving one of the key challenges of controlled nuclear fusion — plasma instability in tokamak-type reactors. «Controlled nuclear fusion is considered an almost inexhaustible source of energy. One of the most promising devices for achieving it is the tokamak fusion reactor. However, due to plasma instability, scientists have so far been unable to achieve economically viable nuclear fusion,» the researcher explained. According to the scientist, the magnetic field lines around the circular current in tokamaks also naturally take this shape.
