摘要： A cryogenic cold head (18) in a canister (14) is partially surrounded by an isolation mass (32). An open portion of the mass (32) permits access for connection of a vapor compression refrigeration unit (22) to the cold head (18), which is highly conductive. Straps (34) of braided copper suspend the isolation mass (32) from the cold head (18), made cold by the refrigeration unit (22). A temperature differential between the cold head (18) and a device-mounting interface (38) on the isolation mass (32) is preferably less than 2.5K per watt of heat transferred. For further vibration isolation, the device (12) is separated from the isolation mass (32) by another braided strap (24) and supported in the canister (14) by struts (16).
摘要翻译：罐（14）中的低温冷头（18）被隔离块（32）部分地包围。质量块（32）的开口部分允许进入蒸气压缩制冷单元（22）到高度导电的冷头（18）的连接。编织铜带（34）将隔离块（32）从冷头（18）悬挂下来，由冷却单元（22）冷却。冷头（18）与隔离质量块（32）上的设备安装接口（38）之间的温度差优选小于2.5K每瓦传递的热量。为了进一步振动隔离，装置（12）通过另一编织带（24）与隔离质量块（32）分离并且通过支柱（16）支撑在罐（14）中。
