Abstract
A magnetic field generating assembly comprises a superconducting magnet located in a cryostat defining a bore accessible from outside the cryostat, and a mechanical refrigerator having at least two cooling stages for at least partly cooling the cryostat. A coolant path extends from the refrigerator into the magnet bore. The coolant path is coupled for heat exchange with a cooling stage of the refrigerator other than the coldest cooling stage, so that the refrigerator is adapted also to cool coolant in the coolant path.
