[en] The system contains a superconducting connector consisting of two sections with separate control. To the extreme outlet of one section is connected a power supply and to the extreme outlets of the superconducting connector is connected the shunt for the dissipation of energy from the superconducting magnet in case of its transition into normal state. In this arrangement the paths are separated for supply and outlet of the energy from the system, which makes it possible to draw energy from the magnet at any moment in time, this both during the current supply and outlet and in autonomous mode.
