DEVELOPMENT OF A HIGH RIGIDITY SUPERCONDUCTING MAGNET FOR THE MAGLEV SYSTEM

A high rigidity type superconducting magnet (SCM) is developed and tes ted by an electromagnetic vibration simulator which simulates the actu al running conditions. To reduce the increase in heat load due to the vibration of the cryostat, several kinds of design concepts are chosen . It is recognized from the experiment result that the most effective design concept is to increase the characteristic frequency in twisting mode of the inner vessel with the high rigidity outer vessel.
