ABSTRACT:
A charged-particle beam electric field deflector includes plural (n) pairs or sets of facing deflection electrodes to accelerate and deflect the beam. Different d.c. acceleration voltages are superimposed on a common deflection voltage and applied to the electrode pairs so that electrode pair k is responsive to acceleration voltage k and the common voltage, where k is selectively each of 1 . . . n. The distance between each pair of facing electrodes is constant or increases along the beam path, while the length of each of the deflection electrodes has a given relationship as a function of the distance between the facing electrodes of each pair. The deflector is used in a flat CRT.
