Abstract
A superconducting magnet includes: a superconducting coil; a coolant container; a radiation shield; a vacuum container; a refrigerator configured to cool the inner part of the coolant container and the radiation shield; a first exhaust pipe connected to the coolant container from the outside of the vacuum container and serving as a flow path of the coolant vaporized; a first pressure release valve connected to a distal end of the first exhaust pipe outside the vacuum container and configured to open when a pressure in the coolant container becomes a first set value or higher; a heater provided at the first exhaust pipe and configured to heat the first exhaust pipe; and a detector provided at the first exhaust pipe and configured to detect a change due to occurrence of freezing in the first exhaust pipe.
