Abstract
An electron beam deflection structure for a high frequency cathode-ray tube incorporates a meanderline slow wave circuit that is supported directly by the same glass rods used to support other portions of the CRT's beam forming and deflection system. To accomplish this, elongate loops that serially interconnect a plurality of deflection plate segments are bent away from the plane of the segments (and the beam axis) and joined by integral support strips to the rods. The elimination of a separate support structure for the deflectors greatly reduces manufacturing costs.
