Abstract :
The first model magnet system of the shielded pulsed superconductive energy storage was designed and constructed to test the shielding effect. The capacity is 200 kJ. The superconductive coil was designed as a usual dc magnet. The rated current was decided as 1,350 A not to be large heat leak through power leads. The shield coil was divided into 12 blocks which were wound in a solenoid type. These blocks were distributed in optimum distribution not to generate magnetic field on the superconductive coil. This enables the construction of such small scaled shield coil. The system is designed to be able to generate energy of 250 kJ in the duty factor of 0.2 %. The field was measured and well agreed with the calculated one.
