Development of a superconducting magnet for simplified ground coils

摘要

In the superconducting Maglev system, it is important to reduce the costs to realize a commercial system. Simplifying the structure of ground coils is effective to reduce the costs, but the harmonic magnetic fields caused by ground coils increase. The on-board superconducting magnets vibrate due to these harmonic fields. Excessive vibration gives rise to large heat loss. We have studied a superconducting magnet for simplified ground coils, hi this paper, we report the design of the superconducting magnet, including the results of emplacement tests and several analyses.
