The High Field Laboratory for Superconducting Materials (HFLSM), Institute for Materials Research, Tohoku University has demonstrated the first practical cryocooled superconducting magnets using a GM-cryocooler and high temperature superconducting current leads. For high magnetic field research, various kinds of easy-to-operate cryocooled superconducting magnets such as wide bore, high field, and new functional magnets have been constructed. Recently, the HFLSM succeeded in developing a cryocooled 18.1 T high temperature superconducting magnet and a cryocooled 27.5 T hybrid magnet. This paper reviews cryocooled superconducting magnet technology and relevant new research areas.
