摘要： 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.

摘要： A superconducting magnet device includes a tubular cryostat defining a central cavity therein, a first superconducting coil set and a second superconducting coil set disposed outside the central cavity and inside the tubular cryostat, and a power supply system being capable of controlling a magnitude of a first exciting current to the first superconducting coil set and a magnitude of a second exciting current to the second superconducting coil set independently of each other. The first superconducting coil set generates a magnetic field distribution, which is convex downward on an X axis and convex upward on a Y axis when the first exciting current is supplied, in the central cavity. The second superconducting coil set generates a magnetic field distribution, which is convex upward on the X axis and convex downward on the Y axis when the second exciting current is supplied, in the central cavity.
