Abstract
A cryostat () with a magnet coil system including superconductors for the production of a magnet field Bin a measuring volume () has a plurality of radially nested solenoid-shaped coil sections () which are electrically connected in series, at least one of which being an LTS section () with a conventional low temperature superconductor (LTS) and at least one of which being an HTS section () including a high temperature superconductor (HTS), wherein the LTS section () is located in a first helium tank () of the cryostat () along with liquid helium at a helium temperature T<4 K. The apparatus is characterized in that the HTS section () is disposed radially within the LTS section (,) in a separate helium tank () of the cryostat () having normal liquid helium and is separated from the LTS section () by means of at least one wall disposed between the two helium tanks. An HTS coil section can be maintained in the cryostat in accordance with the invention over a long period of time and in a reliable fashion.
