Abstract

An assembly for magnetic field generation in a magnetic resonance tomography apparatus has a device for generation of a basic magnetic field, a vacuum vessel surrounding the basic field device and a device for generation of at least one gradient magnetic field. The assembly has a volume with a reduced magnetic field strength in a region between windings of at least one superconducting coil of the basic field device and a non-conductive wall of the vacuum vessel. The gradient field device is fashioned as a superconductor and is at least partially accommodated in this volume.
