Abstract :
Two schemes are proposed for superconducting magnet protection. The first is a self-protection scheme for high-current-density conductors using a metallic structure such as beryllium to act as a transformer secondary, with the conductor winding acting as the primary. A dump resistor is proposed as the second protection scheme for comparison. It requires the use of a lightweight high-temperature dump resistor with the current density limited to 15 kA cm2. The self-protection scheme is being developed for spaceborne and mobile magnet systems
