摘要：

A superconducting magnet with a 0.01% electric power loss was developed. This magnet is used to store electric power as magnetic energy and to stabilize an electric power system This magnet of 78cm outer diameter and 27cm width. consists of 18 double-pancake type coils, and is designed at 10 T/sec pulse-discharge speed. 350A transportation current. To reduce energy loss caused by the eddy current. the copper wire stabilizer, surrounding the superconducting material is subdivided by a cupronickel layer and to prevent quench, cooling channels are arranged between pancakes of the magnet and between turns of the coil. Elementary analysis and tests of mechanical strength, insulation, cooling, and quench were performed, and the performance of this magnet was confirmed with high speed charge -discharge tests and forced-deenergizing tests.
