Abstract

PURPOSE:To enable rapidly discharge externally the stored energy of a large- sized superconductive magnet by connecting a protecting resistor between the current lead conductors of respective superconductive subcoils and connecting a switch in parallel with the resistor. CONSTITUTION:Superconductive subcoils 11-13 forming a single magnet are contained in a cryogenic container 2, and current input conductors 11a-13b are externally led out of the container 2. Protecting resistors 21, 22 are respectively connected to between conductors 11b, 12a, and 12b, 13a, and switches 31, 32 are connected in parallel with resistors 21, 22. In this structure, the switches 31-33 are closed at the normal time, and currents are supplied from an exciting power source 5 to the coils 11-13. When a coil current is discharged for protection, a superconductive magnet can be protected by opening the switches 31-33. According to such a structure, the protecting resistance value can be increased, and hence the discharging time constant can be shortened.
