Abstract
An NMR spectrometer comprising a magnet coil system disposed in the helium tank () of a cryostat and an NMR probe head () which is disposed in a room temperature bore of the cryostat and contains a cooled RF resonator () for receiving NMR signals from a sample to be examined, wherein the helium tank () and the NMR probe head () are cooled by a common, multi-stage, compressor-operated refrigerator, is characterized in that the common refrigerator comprises a cold head () and several heat exchangers () at different temperature levels, wherein the refrigerator is disposed at a spatial separation from the cryostat in a separate, evacuated and thermally insulated housing (), and several cooling circuits () having thermally insulated transfer lines () are provided between the housing () containing the heat exchangers () and the cryostat, and also between the housing () and the NMR probe head (). The probe head and magnet cryostat of the inventive NMR spectrometer can thereby be cooled by a common refrigerator, wherein the cooling resources of the used refrigerator are optimally utilized.
