According to one embodiment, there is provided a method of manufacturing a high-frequency acceleration cavity component, the method including covering a mold with a conducting material, enclosing, in an outer shell, the mold covered with the conducting material, vacuum-airtight-welding the outer shell enclosing the mold, conducing hot isostatic pressing of the vacuum-airtight-welded outer shell, and taking the conducting material formed in the mold out of the outer shell which has undergone the hot isostatic pressing.

Method of manufacturing high-frequency acceleration cavity component

A superconducting magnet device for a single crystal pulling apparatus is arranged outside a pulling furnace containing a crucible for melting a single crystal material therein so as to apply a magnetic field to the melted single crystal material. The superconducting magnet device for a single crystal pulling apparatus includes a cryostat containing a superconducting coil therein, and a refrigerator port arranged on the outer circumferential surface of the cryostat and provided with a cryogenic refrigerator that cools the superconducting coil. The cryogenic refrigerator is provided in a region of the outer surface region of the cryostat at which the intensity of the magnetic field generated by the superconducting coil is weak.
