HIGH MAGNETIC-FIELD FACILITIES AND RESEARCH AT HEFEI

The project for constructing a 20 T hybrid magnet system at the Institute of Plasma Physics, Academia Sinica, was started in 1984 and the hybrid magnet consisting of a NbTi superconducting coil and a water-cooled Bitter coil with 32 mm working bore was first tested in May 1992 producing a steady field of 20.2 T. This installation is now available for scientific experiments. The laboratory also provides water-cooled magnets with fields up to 14 T at two magnet sites and a NbTi superconducting magnet capable of producing 7.5 T in a 10 cm bore for the users. Studies on high T(c) superconductors, magnetic materials, low-dimensional organic conductors, etc., have been conducted in high fields. In the paper the laboratory facilities together with some results of research obtained are reported.
