Abstract
The superconducting magnetic system comprises a superconducting sectionalized coil. Each section of the coil has a series-connected disconnector with a controlled shunt of superconducting material and normal zone detection unit connected in parallel to the coil section and its disconnector. Said coil is linked inductively with an energy removal device. The latter comprises a heat-insulated compartment cooled to cryogenic temperature. The compartment contains the disconnectors and at least one coil of normal metal and a jumper of superconducting material making up a closed electric circuit. Each controlled shunt and jumper is fitted with a control winding. The control windings of the shunts are linked electrically with the respective normal zone detection unit. The control winding of the jumper is linked electrically with each normal zone detection unit.
