Abstract
An electromagnetic deflection yoke includes saddle wound horizontal deflection coils mounted to a liner. The vertical coils are toroidally wound on a smooth, magnetically permeable core having the form of a segmented frusto-conic section and are in contact with the opposite side of the liner. Each vertical coil comprises a repeatable multilayer precision stack of wire turns with only the wire turns providing the support for maintaining the multilayer precision stack. The core has positioning notches which mate with locating tabs on the liner and provide for an accurate positioning of the vertical deflection coils with respect to the horizontal deflection coils.
