Abstract
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 (4b, 4c) and an HTS partial coil (4a, 4d). The LTS partial coil (4b, 4c) can be separately short-circuited in a pure LTS circuit (14b) via an LTS switch (15b), and the HTS partial coil (4a, 4d) can be separately short-circuited in a pure HTS circuit (14) via an HTS switch (15a) and both partial coils (4a, 4d; 4b, 4c) are connected via an LTS-HTS joint (20) and are charged by the same power supply.
