Abstract
The present invention is an improvement in an electron gun assembly. Such a gun assembly includes a plurality of indirectly heated cathode assemblies and at least two spaced successive electrodes having aligned apertures therein for passage of a plurality of electron beams. The cathode assemblies include a plurality of cathode heaters which are attached to at least two electrically insulating support rods by a plurality of heater bead straps. Each of the heater bead straps includes a main body portion having a distal end and a proximal end. The proximal end has a bifurcated portion comprising a pair of closely spaced apart grasping members for embedment into one of the insulating support rods. At least one member of the pair of grasping members is angulated with respect to the main body portion to increase the retention of the heater bead straps to the insulating support rods.
