SUPERCONDUCTING EQUIPMENT

摘要

PURPOSE:To prevent the increase in evaporation of a refrigerant and the appearance of quench of a permanent current switch by supporting a refrigerant box wherein the permanent current switch is stored by a vacuum chamber through a heat-insulating load supporting body for preventing vibration of the permanent current switch and the refrigerant box. CONSTITUTION:A refrigerant box 6 to store a permanent current switch 5 in a refrigerant is located apart from a refrigerant bath 2 to store a superconducting coil 1 in a refrigerant so that mechanical vibration of the refrigerant bath 2 may not work on the refrigerant box 6. The refrigerant bath 2 and the refrigerant box 6 are connected by bellows in vacuum and the refrigerant box 6 to store the permanent current switch 5 is supported by a vacuum chamber 4, using a load supporting body 11. By this structure, the refrigerant box 6 and permanent current switch 5 is independently supported by the heat-insulating load supporting body 11. Therefore, the refrigerant box 6 is not influenced by vibration of the refrigerant bath 2 and so the vibration of the refrigerant box 6 can be considerably reduced.
