摘要： A superconducting high-field magnet coil system comprising several radially nested main coil sections (1, 2, 3, 4, 5) which are connected to each other in series in such a fashion that currents of the same direction flow through them during operation, wherein a first main coil section (EHS) is disposed radially further inward than a second main coil section (ZHS) and at least one intermediate main coil section (ZW) is disposed radially between the first and the second main coil section (EHS, ZHS), and with a superconducting switch (11) via which all main coil sections (1, 2, 3, 4, 5) can be superconductingly short-circuited in series, is characterized in that the first main coil section (EHS) and the second main coil section (ZHS) are directly successively series-connected and the first main coil section (EHS) and the second main coil section (ZHS) are bridged by a common quench protection element, which does not bridge the at least one intermediate main coil section (ZW). The magnet coil system realizes quench protection for selectively preventing excess currents in magnet coil areas in which the excessive mechanical force load associated with an excess current would damage the superconductor.

摘要： A cryostat configuration has a magnet coil system (2) disposed in a helium tank (1), and a horizontal room temperature bore (3) which provides access to a volume under investigation in the center of the magnet coil system (2). The helium tank (1) contains undercooled liquid helium at a temperature of less than 3.5 K, in particular of approximately 2 K, and the cryostat configuration has at least one vertical tower structure (4) on its upper side for filling in and evaporating helium. The tower structure (4) contains a container (5) with liquid helium of 4.2 K which is separated from the helium tank (1) by a thermal barrier (7), and the helium tank (1) contains an undercooling unit (9). This yields a compact cryostat configuration which achieves continuous, stable long-term operation with an undercooled high-field magnet coil.
