Description

technical field [0001] The invention relates to a superconducting magnet arrangement with a cooling chamber containing a cooling medium. Background technique [0002] Generally, regarding a superconducting magnet device, a superconducting magnet is composed of a main coil and a shielding coil. The main coil generates a magnetic field mainly in the magnetic field space and is wound around the main coil frame. The shielding coil suppresses the leakage of the magnetic field generated by the main coil to the It is outside the device and wound on a shielding coil frame. Such a superconducting magnet is installed and cooled in a cooling chamber containing a cooling medium. [0003] As such a superconducting magnet device, for example, a device as described in Patent Document 1 is known. In Patent Document 1, a superconducting magnet device is disclosed, which is equipped with a main coil, a shield coil, and a supporting member in a cooling chamber. The bobbins are arranged subs...
