CURRENT INTRODUCTION TERMINAL FOR CRYOSTATIC EQUIPMENT

摘要

PURPOSE: To reduce AC loss on conduction in a support fitment of a current introduction terminal for cryostatic equipment. CONSTITUTION: In a current introduction terminal for cryostatic equipment where a conductive part 1 is constituted so that it is supported by a cooling container 6 via an insulation member 4 and a stress absorption member 2, one edge of the insulation member 4 is connected to the cooling container 6 via a support fitment 5 and the other edge is connected to the stress absorption member 2 via a support fitment 3 of a nonmagnetic material, thus making connection to the conductive part 1 via the stress absorption member 2. The support fitments 3 and 5 of nonmagnetic material are constituted by copper nickel.
