Superconducting magnet coil system with quench protection to avoid local current via projections

摘要

A superconducting high field - magnet coil system, comprising- a plurality of radially interleaved main coils sections (1, 2, 3, 4, 5), which are connected in series with one another in such a way that, during operation of same direction current flows through,a first main coils section (ehs also called) lies radially further inward than a second main coils section (zhs), and radially between the first and second main coils section (ehs also called, zhs) at least one between - main coils section (zw) is arranged,- and a superconducting switch (11), over which all of the main coils sections (1, 2, 3, 4, 5) can be superconductingly short-circuited in series,is characterized by the,that the first main coils section (ehs also called) and the second main coils section (zhs) in the serial electrical connection to follow directly one after the other, and in that the first main coils section (ehs also called) and the second main coils section (zhs), but not the at least one between - main coils section (zw), of a common quench protection element are bridged.In the inventive magnet coil system can be a quench protection can be produced with the magnet coils regions in which the with an excess increase of the mechanical load which is connected to a damage of the superconductor would lead, a current can be prevented in a targeted manner.
