The electromagnetic traps have unique properties favourably distinguishing them from others thermonuclear systems. The application of the combined electrical and magnetic fields allows to solve a problem of plasma stability, to receive close to classical factors of particles and energy cross transfer. Energy recuperation in an electrical field facilitates an exit of reactor on a stationary mode supported at the expense of direct transformation of kinetic energy of -particles in electrical one. Ions oscillation in a radial electrical field of a potential well, them focusing essentially reduces the requirements to a boundary magnetic field, allows to use a less power-intensive magnetic systems.
