PURPOSE:To provide a title apparatus of high reliability and simple structure which can cool a joint by utilizing a phase change in the same fluid without providing a control valve to depressurize a high tension fluid by removing a partition wall which separates a high tension supercritical helium and low tension helium. CONSTITUTION:This apparatus has a forced cooling superconducting coil connected from a forced cooling conductor 2 to a current lead body energizing division 11, makes the space rate of the forced cooling conductor at the joint smaller than that of the in-coil conductor, and forms a volume enlargement division 13 at the joint. |
