Abstract
A cryostat arrangement includes a superconducting magnet to be cooled by an active cryocooler. The cryocooler includes a coolant circuit with a compressor, a cold head, and a cold finger in thermal contact with the magnet. A volumetric vessel containing cryogenic fluid is thermally coupled to the magnet. The volumetric vessel is connected to the coolant circuit by a pressure-resistant line. A fluidic component influences the flow rate through the line in a defined manner such that the cryogenic fluid flows between the volumetric vessel and the coolant circuit with a time constant of at least 15 minutes. The cryostat can be operated in a 'cryogen-free' manner and permits a sufficiently long time to quench in the event of operational malfunctions.
