Abstract: A small-sized high-precision superconducting magnet apparatus which can prevent an occurrence of the principal factor in generating a quench and can restrain the magnetic flux from varying with time, and a method of regulating the magnetization of such a superconducting magnet apparatus, by which the superconducting magnet apparatus can be uniformly magnetized. Superconducting magnet apparatus of the present invention has: a cooling container; a holding medium for holding a persistent current therein, which is placed in said cooling container and is operative to generate a magnetic flux in a uniform magnetic field region (FOV); static-magnetic-field generating means composed of a plurality of cylinders using superconducting composite plate materials; a cylinder supporting base for holding the plurality of cylinders; and temperature regulating devices (not shown in FIG. 67) embedded in the cylinders, respectively.

Abstract: In X-ray apparatus utilizing a rotary anode type X-ray tube in which a rotary anode provided with a target is rotated by a rotor driven by a stator on the outside of the tube, the stator windings are energized by a single phase or three phase alternating current source and high positive potential is applied to the anode electrode and one of the stator windings so as to eliminate an insulator between the anode electrode and the stator.
