This paper reviews cryogenic systems in High Field Laboratory for Superconducting Materials, where three superconducting magnets (SM-3, SM-2 and SM-1) in hybrid magnets (HM-3, HM-2 and HM-1) and four superconducting magnets are separately operated. Two helium liquefier-refrigerators and an automatized helium gas recovery system are provided for operations of these magnet systems and experimental performances, for which a large amount of liquid helium is consumed. SM-3 and SM-2 are precooled by use of cryogenerators (PGH 105), while helium liquefier-refrigerators are used to cool down SM-1 and to supply liquid helium to it. Supply of liquid helium to all the superconducting magnets are done by use of several storage vessels.
