ABSTRACT:
An in-line electron gun assembly for a color television picture tube has a center cathode disposed between two outer cathodes. Each cathode is supported by a cathode support assembly comprising a cathode eyelet and a beading support member. Each beading support member varies in dimensions as a function of temperature and the center beading support member stabilizes at a higher operating temperature than the outer beading support members. The ends of the beading support members are embedded in a pair of oppositely-disposed insulating support rods. The center beading support member is formed of a material having a low thermal expansion coefficient and the outer beading support members are formed of a material having a higher thermal expansion coefficient. The materials are chosen such that the outer beading support members expand more than the center beading support member but substantially equal to one another so that the cathodes are rigidly affixed to the support rods.
