Abstract
Fusion reactors need liquid nitrogen and liquid helium for the superconducting magnets and for vacuum pumping. Materials properties at low temperatures must be taken into account in designing cryogenic systems. Cryogenic systems for refrigeration and liquefaction are well developed, but complex and expensive. Thermal insulation is provided by multilayer reflective metallized plastic films in vacuum. The ITER cryogenic system will provide an average cooling power of 65 kW at 4.5 K, and liquid helium will be stored in a 120 m3 dewar.
