ABSTRACT:
An enhancer for enhancing the horizontal deflection of an electron beam in a kinescope includes a quadrupole deflector. The quadrupole deflector is orientated so that the convergent action occurs in the same plane as the horizontal deflection. The divergent action is substantially decreased by utilizing additional members to shunt out the magnetic field which causes the divergent action.
