Patent ID: 8467841

Claim:
A superconducting high-field magnet coil system having several radially nested main coil sections which are connected to each other in series in such a fashion that currents of a same direction flow through them during operation, the system comprising: a first main coil section; a second main coil section disposed radially further outward than said first main coil section; at least one intermediate main coil section disposed radially between said first and said second main coil sections; a superconducting switch disposed, structured and dimensioned to superconductingly short-circuit said first, said second and said intermediate main coil sections in series; and a quench protection element, said quench protection element bridging said first and said second main coil sections, wherein said first main coil section and said second main coil section are directly successively series-connected and said quench protection element does not bridge said at least one intermediate main coil section.
