Helium / hydrogen refrigeration for the ISIS Second Target Station

Air Liquide has designed and implemented the cooling system for the new generation of spallation neutron sources (the ISIS Second Target Station) in the United Kingdom. The equipment involved will keep two neutron moderators at 20K, one consisting of a cavity filled with solid methane and the second of a double cavity filled with solid methane and liquid hydrogen.
