Superconducting coil having a granular superconducting junction

摘要

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.
