Preliminary Design of the End Plug Magnet System for a Tandem Mirror Reactor

摘要

A conceptual design of the end plug magnet system for a tandem mirror reactor is presented. An innovative approach is needed, particularly in the Yin Yang coil, to satisfy the requirements of an adequate mirror ratio, high field (14 to 17 Tesla), high current density and the unusual geometry. Nb sub 3 Sn superconductor is used and superfluid cooling is adopted to provide cryostability at the required high current density. The stabilizer used is high strength copper or stainless steel encased high purity aluminum. External structure is provided with heavy casings which surround the Yin Yang coils and are joined to each other at critical locations. (ERA citation 05:017223)
