STUDY ON THE REDUCTION OF CURRENT FOR A HIGH-FIELD SUPERCONDUCTING MAGNET BY USING A SUPERCONDUCTING TRANSFORMER

Generally speaking, a high field superconducting magnet like a dipole magnet needs a large excitation current, and its equipment for current excitation becomes very large and complicated for operation. So the a uthors have developed a magnetic system composed of a superconducting magnet and a superconducting transformer basically used for the reduct ion of the excitation current(1). In this study, a fundamental test of the magnet system has been conducted to examine the working principle , and the effectiveness of this system was verified together with the possible reduction in excitation current for the high field supercondu cting magnet.
