Abstract
A superconducting magnet device includes a superconducting coil disposed in a cryogenic environment; and a protection diode disposed in the cryogenic environment and connected to the superconducting coil, the protection diode being disposed such that a direction of a magnetic field generated by the superconducting coil on a pn junction surface of the protection diode forms an angle within about 30 degrees with respect to a normal line of the pn junction surface.
