Abstract: PURPOSE:To obtain a stable deflection electromagnet for an acceleration ring with the temperature rise of an end part adjusting piece due to eddy current restrained by making the lamination direction of a laminated iron core parallel to an end surface to which an end part adjusting piece is fitted, and orthogonal to the direction of magnetomotive force generated with an exciting coil woundly mounted on upper and lower magnetic poles respectively. CONSTITUTION:End part adjusting pieces 51 and 52, fitted to both end surfaces orthogonal to the travel direction of an electron beam of an upper magnetic pole 11 and a lower magnetic pole nipping a gap part, are composed of a laminated iron core laminated with laminated steel plates. Moreover the lamination direction of the laminated iron core is made so as to be parallel to an end surface, to which end part adjusting pieces 51 and 52 are fitted, and orthogonal to the direction of magnetomotive force generated with an exciting coil 2 woundly mounted on upper and lower magnetic piles respectively. Consequently because the end part adjusting pieces 51 and 52 smoothly passes magnetic flux in the direction of the magnetomotive force, eddy current 200 flowing the surface vicinity of the upper and lower magnetic poles is blocked with an insulation layer between steel plates, therefore the eddy current 200 does not flow in the end part adjusting pieces 51 and 52. This eliminates the occurrence of local heating in the end part adjusting pieces 51 and 52 to obtain a stable and high reliable deflection electromagnet for an acceleration ring.
