Conduction cooling device and conduction cooling method

摘要

PROBLEM TO BE SOLVED: To efficiently cool a superconducting coil and a permanent current switch (PCS) within a short time, during an on-state or an off-state of the PCS.SOLUTION: A conduction cooling device includes: a cryogenic refrigerator 2; a superconducting coil 1; and a permanent current switch 3 thermally connected to the cryogenic refrigerator via a heat transfer member 5 for a permanent current switch. The heat transfer member for a permanent current switch includes two or more connection terminals 61, 63 and a flexible heat transfer body 51 provided between the connection terminals. At least one connection terminal 62 of the connection terminals is movable.SELECTED DRAWING: Figure 1
