0.5 MJ superconducting pulse magnet for energy storage

Laboratory for Applied Superconductivity was started in FY 1980 in Osaka University. The main objectives of laboratory are to develop the basics of the technology of superconducting magnet; superconducting material, control system, and energy application of superconducting magnet such as energy storage. The system of pulsed superconducting coil is the main facility of the laboratory. The specifications of the magnet are; I.D.: 30 cm, O.D.: 49 cm, Height: 25.5 cm, Stored energy: 515 KJ, Central field: 5T, dB/dt: 5 ∼ 7 T/s.
