Abstract

PURPOSE:To prevent the rise of temperature of series-connected superconducting coils for improvement of their reliability by heating in succession forcedly- quenching heaters by means of the voltage of the superconducting coils generated by quenching, each said heater being disposed in each cryostat in which each said superconducting coil is housed independently of the other superconducting coils. CONSTITUTION:Each of series-connected superconducting coils 2a-2d is housed in each of independent cryostats la-ld together with each of heaters 3a-3d connected in parallel with each of the coils 2d-2a. Once in this situation quenching of the coil 2b is detected to close a circuit breaker 4 followed by propagation of the quenching in the coil 2b, the coil 2b generates voltage thereacross owing to ordinary conduction resistance. This voltage energizes the heater 3a to cause quenching where a fraction of the coil 2a exceeds critical temperature, and likewise the coils 2d, 2c are quenched in succession. Hereby, associated energy is uniformly consumed through the superconducting coils without being consumed only by the quenched superconducting coils to prevent temperature rise as well as prevent burning of those superconducting coils, for improvement of reliability of the device.
