    摘要: To provide a magnetic field control apparatus capable of reducing a width of a correcting plate. The magnetic field control apparatus includes a conductive vacuum duct 1 disposed between dipole magnet magnetic poles 3 and a conductive correcting plate 2. The correcting plate 2 is formed of a material having an electric conductivity higher than that of the vacuum duct 1. A plurality of conductive correcting plates 2 are disposed in each of four areas, the four areas being formed by dividing a cross section of a vacuum duct 1 extending perpendicularly to a direction in which a charged particle beam travels by a symmetrical surface having each of both magnetic poles of the dipole magnet defined as a mirror image and a plane which extends perpendicularly to the symmetrical surface and through which a center of gravity of the charged particle beam passes.
