Abstract
A superconductive coil assembly has a housing formed of an inner shell and an outer shell, and a superconductive coil situated in a space defined between the shells. A plurality of spring elements arranged in a mosaic-like pattern on a surface area of one of the shells between the superconductive coil and the shell. Each spring element has a first flat member being of a material having a relatively small dilatation and a second flat member being of a material having a relatively large dilatation. The first and second flat members are inseparably bonded to one another. The spring elements have an effective thickness that is greater at a relatively low temperature than at a relatively high temperature.
Claims3
In a superconductive coil assembly having a generally D-shaped housing formed of an inner shell and an outer shell surrounding said inner shell, a generally D-shaped superconductive coil situated in a space defined between said shells;
- the improvement comprising a plurality of spring elements arranged in a mosaic-like pattern on a surface area on a convex portion of said inner shell between said superconductive coil and said inner shell;
- said spring elements being in a face-to-face engagement with said inner shell and said superconductive coil;
- each said spring elements having a first flat member being of a material having a relatively small dilatation and a second flat member being of a material having a relatively large dilatation, said first and second flat members being inseparably bonded to one another;
- said spring elements having an effective thickness that is greater at a relatively low temperature than at a relatively high temperature.
