A coil having superconducting windings cooled without cryogenic fluids

摘要

A coil comprises a set of windings (30; 30'; 30") with a generally annular shape and formed by a plurality of series-connected partial windings (301; 301'; 301") made of a superconductor with a high critical temperature, in which these partial windings are arranged next to each other in stratified form, and at least one cooling sheet (350; 350'; 350") which is made of thermally conductive material and arranged in contact with this set of windings and which is designed to be connected in a thermally conductive manner to a cryogenic cooling system (60).
