Superconductors for Pulsed Magnets

The possibility of using superconducting pulsed magnet for high energy physics has been studied in many laboratories around the world. Problems and requirements of the pulsed magnets tested in those laboratories are reviewed in conjunction with conductors developed for them. Most serious problems involved in the pulsed magnets are degradation and training effects. Brief reviews on AC losses and stability are also given. Design requirements of the conductors for the pulsed magnets are considered in terms of several parameters, such as number of filaments, diameter, Cu/SC ratio, alloy compositions and twist pitch. Since requirements of the conductors for high stability and low AC losses are conflicting, some of the parameters are optimized.
