Abstract: A superconducting apparatus is provided with a cryostat, a superconducting magnet contained in the cryostat, an emergency gas discharge pipe connected with the cryostat, and an emergency discharge valve disposed midway of the discharge pipe for discharging to an external environment an emergency discharge gas generated at quenching. In addition, the superconducting apparatus is provided with a gas heating unit for heating the emergency discharge gas flowing inside the discharge pipe.

Abstract: In a bending magnet, a core which is substantially sectoral or semi-circular in horizontally sectional configuration and in which opposed magnetic poles are formed and a vacuum chamber for storage of a charged particle beam is disposed in a gap between the opposed magnetic poles, and a pair of upper and lower exciting coils for generating a bending magnetic field in the gap between the magnetic poles of core, the reluctance against the magnetic flux passing through a portion of the core adjacent to the inner circumference of the orbit of the charged particle beam and a portion of the core adjacent to the outer circumference of the charged particle beam orbit is equally uniformed over the overall length of the orbit of the charged particle beam.
