We have been developing and installing several high field magnets, i.e. long pulsed magnets, a 40 T class hybrid magnet, a 21 T superconducting magnet, several high resolution magnets, etc. The 40 T class hybrid magnet is composed of a 15 T superconducting magnet with a room temperature clear bore of 400 mm and a 25 T polyhelix-type water-cooled magnet with a 30 mm bore. The 21 T superconducting magnet with a clear bore of 61 mm, operated at 1.8 K, is now being used. Inside the magnet small Bi-2212 coils have been installed and excited to generate a total field up to 21.8 T in a clear bore of 13 mm. Using the high resolution magnet systems, Fermi surface properties of many materials have been revealed. Furthermore, we have fabricated two types of pulsed magnet coils to generate 73.4 T in a short pulse duration of 5 ms and 64.5 T in a long 100 ms duration, using newly developed Cu-Ag alloy composite wires with high strength and high conductivity.
