A magnet structure for use in a circular ion accelerator, such as e.g. a synchrocyclotron comprises a cold-mass structure including superconducting magnetic coils (), at least one dry cryocooler unit () coupled with the cold-mass structure for cooling the latter and a magnetic yoke structure () with a return yoke () configured radially around said coils (). The return yoke () comprises an opening in which said dry cryocooler unit () is received so as to be in thermal contact with said cold-mass structure.

Magnetic structure for circular ion accelerator

A coil comprises a set of windings with a generally annular shape and formed by a plurality of series-connected partial windings 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 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.

Coil with superconductive windings cooled without cryogenic fluids

A superconducting coil comprises a plurality of windings. Each winding comprises at least one superconducting segment having an exposed area containing a granular superconducting substance. A junction electrically connects at least one superconducting segment of one winding to at least one superconducting segment of another winding. The junction is formed by coupling the granular superconducting substance of the exposed area of the at least one superconducting segment of the one winding to the granular superconducting substance of the exposed area of the at least one superconducting segment of the other winding. In an embodiment, the exposed areas are positioned to face each other.
