The various components, namely the different vessels contained within each other for housing the superconducting magnet, or the liquid comprising a cryostat or storage tank for cryogenic liquids are generally either suspended or supported by each other. Thus, a support/suspension system has various tasks, besides carrying the magnet or shield loads, it also keeps the position of the cold mass during shipping and also fixes the internal clearances between the radiation shields during installation as well as repeated cooldown. The various constraints put onto these suspension systems result in an increased input of heat into the cryostat depending on the overall size of cryostat and superconducting magnet system. Various parts of the cryogenic components such as radiation shields have to be cooled, either by means of using liquids or by using forced convection cooling, or by other external means such as conventional GM-cryocoolers. The present invention therefore provides a new type of support or suspension system which combines the two functions mentioned above, namely supporting or suspending and cooling, and applies these to the pulse tube cooler. The pulse tubes (22-38) could be arranged in series or in parallel, could be single or multi-staged or feature an additional liquefying stage and suspend or support a superconducting magnet or HTS conductor within a cryostat. The pulse tube being either a suspension or support member could also simultaneously cool the shields 26 connected to it and at the same time carry shield or magnet loads.
