Abstract
The objective of the present invention is to provide a conduction-cooling-type super-conducting magnet, wherein a surface pressure is applied between a super-conducting coiled wire portion and a cooling member, the non-uniformity of the surface pressure in the diameter direction of the coiled wire portion has been improved, whereby the uniformity of contact heat resistance has been improved, moreover, warping due to a thermal contraction difference between the cooling member and the coiled wire portion arising at cooling time has been decreased sufficiently, and a surface pressure application mechanism can be installed solely in the low-temperature portion where the super-conducting coiled wire portion is installed. Provided is a conduction-cooling-type super-conducting magnet characterized by: an adequate heat conductor, which is connected to a cooler, in contact with the super-conducting coiled wire portion; the inclusion of an elastic body, which is capable of imparting, in the form of a displacement, an amount of contraction that is sufficiently greater than the amount of contraction of the adequate heat conductor and the wound wire portion at cooling time; and at least one ela…
