More Information
Summary:The refrigerator channel (14) has a sleeve (24) and a base (34). The piping (50) is led out from the refrigerator channel (14). The piping (50) is provided with a valve (52). Before the cold head (16) is pulled out, helium in the tank (58) is supplied to the channel space (42) through the piping (50). As a result, the pressure in the channel space (42) becomes atmospheric pressure or is close to atmospheric pressure. 制冷机通道(14)具有套筒(24)及底座(34)。配管(50)从制冷机通道(14)引出。配管(50)上设有阀(52)。在拔出冷头(16)前，罐(58)内的氦气经由配管(50)供给到通道空间(42)。由此，通道空间(42)的压力成为大气压或者接近大气压。
