ABSTRACT:
A novel electron gun for a cathode-ray tube includes at least one and preferably three cathode assemblies and at least four successive electrodes longitudinally spaced from the cathode assemblies. Each of the electrodes has at least one and preferably three electron beam apertures therethrough. The cathode assemblies and two of the electrodes are attached to a ceramic support member which is the sole supporting interconnection therebetween. A third electrode of the four successive electrodes has a distal electrode member and a proximal electrode member. The proximal member also is attached to the ceramic support member to form a first gun module. A second gun module includes a fourth electrode of the four successive electrodes which is in spaced relation to the distal member of the third electrode. The fourth electrode and the distal member of the third electrode are interconnected by a pair of insulative spacers. The second gun module is secured to the first gun module by fixedly attaching the distal member of the second gun module to the proximal member of the first gun module.
