Abstract
A pulsed magnet for the generation of fields up to 60 T using inductive energy storage has been built, tested and used for experiments at the Grenoble High Magnetic Field Laboratory (GHMFL). The pulse magnet system consists of a magnetic energy storage coil, made from aluminum of rectangular cross-section with a warm bore diameter of 1.1 m. Inside the warm bore is a smaller high-field magnet made from copper wire with a cold bore diameter of 24 mm. An electrical supply network consisting of a shock alternator, transformer and a rectifier provides the storage coil with a maximum dc current of 120 kA. High-current circuit breakers then direct the stored energy into the high field magnet. For safety and redundancy, two independent monitoring systems control the energy transfers. The design layout of the magnet system and the generation of pulses with fields up to 60.3 T with a pulse duration of 100 ms is described.
