Short review on cryostats with superconducting magnets

Abstract

Abstract Modern accelerators typically include many components working at cryogenic temperatures, like superconducting (sc) magnets, sc cavities, cooled beam tube, sc undulators. In most of the cases, sc magnets or cavities are used. Sc magnets were intensively developed over the last 50 years, and it is possible to say that for some sc materials, like NbTi or Nb3Sn, the technology reached a maturity. The sc magnets could be installed either in liquid helium reservoirs or be mounted on metallic structures and passively cooled by the thermal conduction. Though there is a large variety of different types of cryostats, some general requirements posted on them by sc magnets, bus-bars or current leads could be seen. In the present paper a short review on cryostats with superconducting magnets is done as well as general design requirements on bus-bars and safety diodes are shortly mentioned. Two typical cryostat types used for scientific needs or industry applications are discussed. Cryostats with high-Tc current leads or magnets are also shortly mentioned.
