PROTECTION AGAINST SUPERCONDUCTIVITY DISRUPTION IN SUPERCONDUCTING MAGNETS Russian patent published in 2021 - IPC G21B1/05 

FIELD: nuclear physics.

SUBSTANCE: invention relates to the protection against superconductivity disruption in superconducting magnets. A toroidal field coil contains a central pillar, a set of reverse branches, a system of protection against superconductivity disruption and a cooling system. The central pillar contains high-temperature superconducting (hereinafter – HTSC) material. Each reverse branch contains a section capable of superconductivity disruption, two HTSC sections and a system of superconductivity disruption. The system of superconductivity disruption is connected to the section capable of superconductivity disruption and is made with the possibility of disruption of superconductivity of the section capable of superconductivity disruption. The system of protection against superconductivity disruption is made with the possibility of detection of superconductivity disruption in the toroidal field coil and, in response of the detection of superconductivity disruption, encouragement of the system of superconductivity disruption to disrupt superconductivity of the superconducting material in one or more sections capable of superconductivity disruption in order to drop energy from the toroidal field coil to the specified one or more sections capable of superconductivity disruption.

EFFECT: provided is possibility of prevention of HTSC material overheating in the case of superconductivity disruption in the toroidal field coil in the magnetic system in the thermonuclear reactor.
