摘要

Nuclear magnetic resonance - apparatus (10) with a superconducting main zone - magnet coil system (14), which is a homogeneous magnetic field of at least 3 t can be produced, as well as with a gradient coils - a system (15), which is a gradient strength of at least 10 mtm–1 with a rising rate of at least 100 tm–1s–1 , with the main zone - magnet coil system (14) in a cryostat (12) with liquid helium and a refrigerating machine (16) in the form of a pulse tube - cooler or a gifford - mcmahon - cooler is arranged, and wherein a steam outlet conduit (17a, 27a, 37a) for possibly from the cryostat (12) is provided, which is vapor-deposited helium,characterized by the,that the refrigerating machine (16) in all operating states of the nuclear magnetic resonance - apparatus (10) without a gradient switching a cooling effect can, the at least 0,3 w over the entire power loss of the cryostat (12) is,that the steam outlet conduit (17a, 27a, 37a) in a outside the cryostat (12) which is arranged in the buffer vessel (19, 29, 39, 39 '') for the collection of the evaporating helium, andthat a return line (17b, 27b, 37b) for returning the in the buffer vessel (19, 29, 39, 39 '') collected evaporated helium in the cryostat (12) is provided.
