Abstract
A cryostat assembly comprises a liquid coolant containing vessel; a mechanical cooler having at least one cooling stage located above the vessel; and a channel for conveying gaseous coolant from the vessel to the cooling stage where the coolant is condensed in use and then returns through the channel to the vessel. An acoustic wave attenuator is located in the channel for attenuating the passage of acoustic energy originating from the mechanical cooler and propagating through the gaseous coolant, while permitting flow of gaseous coolant to the cooling stage and flow of condensed coolant to the vessel.
