Magnetic systems for fusion devices

Mirror experiments have led the way in applying superconductivity to fusion research because of unique requirements for high and steady magnetic fields. The first significant applications were Baseball II at LLNL HENNING and IMP EFFERSON at ORNL. More recently, the MFTF-B Yin-Yang Coil HENNING was successfully tested KOZMAN and the entire tandem configuration is nearing completion. Tokamak magnets have also enjoyed recent success with the large coil project tests at ORNL HAUBENREICH, preceded by single coil tests in Japan and Germany. In the USSR, the T-7 Tokamak has been operational for many years and the T-15 Tokamak is under construction, with the TF coils nearing completion. Also the Tore Supra is being built in France. (orig.)
