Claim Text:
1. A dock for superconducting magnet excitation comprising: a plant for condensing helium gas to liquid helium; a frame on which a superconducting magnet is mounted; a supply pipe used to send liquid helium from the plant to the superconducting magnet; at least two recovery pipes, with different diameters, to send helium gas from the superconducting magnet to the plant; a power supply for supplying an excitation current to the superconducting magnet; and a power lead which connects the power supply to the superconducting magnet; a constant-pressure valve, which is opened when the pressure in the recovery pipe exceeds predetermined pressure, provided in the recovery pipe with the larger diameter; and a fan for diffusing helium gas emitted when the constant-pressure valve is opened, wherein the recovery pipe with a larger diameter connected to an emergency exhaust hole for exhausting helium gas, which evaporates in the superconducting magnet in the event of a quench, to the outside.
