Abstract
A device for transferring liquid helium into a usage helium tank of a usage cryostat includes a reservoir cryostat with a vacuum-insulated reservoir helium tank configured to store liquid helium available for filling the usage helium tank, a supply line for liquid helium, and a gaseous helium return line. The supply line proceeds from the vacuum-insulated reservoir helium tank and is connected to the usage helium tank. The gaseous helium return line leads into the vacuum-insulated reservoir helium tank and is connected to the usage helium tank. The device further includes a conveying device configured to convey liquid helium from the vacuum-insulated reservoir helium tank through the supply line into the usage helium tank and further configured to convey gaseous helium from the usage helium tank through the return line into the vacuum-insulated reservoir helium tank.
