Abstract

PURPOSE:To prevent breakdown of the coil or a coil container due to evaporated gas even when quenching occurs by providing a recovery chamber which recovers very low temperature refrigerant at a part of a container wherein a coil conductor is enclosed together with the very low temperature refrigerant. CONSTITUTION:The coil conductor 2 which is enclosed in the coil container 1 is immersed in liquid helium in order to cool the heat which is caused by AC losses when a current is conducted and introduced from the outside and to maintain the superconductive state. Normally, a small amount of the liquid helium is supplied through an upper pipe 7 and evaporated gas is recovered to a helium liquid refrigerating device 3 through a pipe 8. When the coil is quenched, it is detected by a pressure detector 9, a separating valve 10 is momentarily opened, and the helium is recovered to a Dewar 11 before most of the liquid helium is heated and evaporated by the coil conductor 2 and stored as the state of liquid helium. Thus the breakdown of the coil container and the like due to the gas being rapidly evaporated is prevented.
