On at least one portion of a path along the vacuum vessel from the first mechanical connection point to the second mechanical connection point and/or on at least one portion of a path along the positioning element from the second mechanical connection point to the shim system, only materials whose thermal expansion coefficient at operating temperature is less than 5 ppm/K are used. Magnetic field homogeneity can thus be kept largely stable and constant.
