PURPOSE:To abate the vibration of a permanent current switch during running step by arranging the permanent current switch in the central part of a superconductive coil racetrack. CONSTITUTION:This superconductive magnet device 1 is composed of a superconductive coil 11 formed in a racetrack shape by winding up a superconductive wire, a permanent current switch 13 for turning a coil current into a permanent current mode, an inner vessel 10a for encircling the superconductive coil 11 and the permanent current switch 13, a shielding plate shielding the radiant heat and magnetic disturbance, a adiabatic supporting bodies 9 interposed between the shielding plate and fixing axles 8, an outer vessel 9 containing respective members for maintaining vacuum state, furthermore, the permanent current switch is to be arranged in the central part of the superconductive coil racetrack in this superconductive device 1. Through these procedures, the title superconductive magnet device 1 having the inner vessel 10a in a symmetrical shape capable of abating the vibration of the permanent current switch 13 to be easily made can be manufactured. |
