Abstract
PURPOSE:To prevent the evaporation of expensive liquid helium whose natural resources are scarce, by making up a permanent current switch with ceramics system high temperature superconducting material which turns to a superconducting state at a liquid nitrogen temperature, and immersing it in the liquid nitrogen. CONSTITUTION:A permanent current switch 33 is accommodated in a cryostat 2a and immersed in liquid nitrogen 11. A superconducting coil is accommodated in a cryostat 2b, and immersed in liquid helium 10 to be turned into a superconducting state. In order to excite a coil 1, the switch 33 is turned into a normal conduction state by making a heater 5 ON, and a current is made to flow from a power supply 7. Then the liquid nitrogen 11 in the cryostat 2a evaporates on account of heat generation of the heater 5, but it gets along without generating other effects. Therefore, helium in the cryostat 2a does not evaporate.
