| 摘要 |
The invention concerns a superconducting high-field magnet system ( 1 ) for a high-resolution magnetic resonance spectrometer, comprising a magnet coil ( 4 ) which is superconductingly short-circuited during operation, and generates a homogeneous temporally stable magnetic field during operation that meets the requirements for taking a high-resolution magnetic resonance spectrum. The magnet coil ( 4 ) comprises an LTS partial coil ( 4 b , 4 c) and an HTS partial coil ( 4 a , 4 d). The LTS partial coil ( 4 b , 4 c) can be separately short-circuited in a pure LTS circuit ( 14 b) via an LTS switch ( 15 b), and the HTS partial coil ( 4 a , 4 d) can be separately short-circuited in a pure HTS circuit ( 14 ) via an HTS switch ( 15 a) and both partial coils ( 4 a , 4 d ; 4 b , 4 c) are connected via an LTS-HTS joint ( 20 ) and are charged by the same power supply.
