Abstract
The invention concerns a magnet configuration comprising a superconducting magnet coil () within which a gradient system is to be switched. All low temperature oscillation systems (R) with a temperature T<10K within the magnet coil () are produced from a material having good electrical conducting properties, and at least one warm oscillation system (R2) with a temperature T>10K within the magnet coil () has worse electrical conducting properties and has a considerably different mechanical resonance frequency (separation approximately 500 Hz or more) than at least one of the low temperature oscillation systems (R). This reduces the undesired heating power supplied to the low temperature oscillation systems due to mechanical oscillations and induced eddy currents.
