ABSTRACT:
An improvement in the means for supporting individually shielded cathodes is provided in a plural beam cathode ray tube electron generating assembly incorporating an in-line electron gun arrangement integrated by four spaced-apart longitudinal insulative rod-like supporting members. Each of the individual all-metal cathode assemblies is separately supported in a spatial manner apart from the related cup-like control electrode wherein a portion of the respective cathode assembly is oriented. The three cathode positioning members have discretely formed extremital portions embedded in the longitudinal supporting member to provide improved shielding and enhanced structural end-support for the in-line gun assembly.
