<p>A cryostat arrangement has a magnet coil system arranged in a helium tank(1) and a horizontal room-temperature boring (3), and where the helium tank (1) contains sub-cooled liquid helium with a temperature of less than 3.5K, especially of approximately 2K. In the tower structure (4) a container (5) holding liquid helium at 4.2K is separated by a thermal barrier from the helium tank (1). In the helium tank (1) is provided a sub-cooling unit (9).</p> |
