Load bearing means in cryostat systems

In cryostat systems, the different vessels contained within each other for housing eg a superconducting magnet, or the cryogenic liquid storage tanks are generally either suspended or supported by each other. The support or suspension systems also fix the internal clearances between radiation shields. The various constraints put onto these support or suspension systems result in an increased input of heat into the cryostat system. A load-bearing support or suspension system which combines two functions, namely supporting or suspending and cooling, comprises at least one pulse tube cooler. The pulse tubes (22-38) may be arranged in series or in parallel, may be single or multi-staged or feature an additional liquefying stage. The pulse tube acts as the suspension or support member, as well as simultaneously cooling any radiation shields connected to it, and at the same time be able to carry magnet loads.
