摘要： An electron gun for a cathode ray tube includes a triode composed of a cathode, a controlling electrode, and a screen electrode. A pre-focusing electrode is provided and supplied with a first voltage for pre-focusing electron beams emitted from the triode. A first auxiliary electrode is provided and supplied with a second voltage which is also supplied to the screen electrode. A second auxiliary electrode is provided and supplied with a third voltage which is also applied to the controlling electrode. The applied voltages create divergent lenses between the focusing electrode and the first auxiliary electrode and between the first and second auxiliary electrode. A main focusing electrode is provided and supplied with the first voltage like the pre-focusing electrode. A converging lens is formed between the second auxiliary electrode and the main lens. A final accelerating electrode is installed adjacent to the main focusing electrode and supplied with a fourth voltage. A main lens is formed between the main focusing electrode and the final accelerating electrode. The electron gun for a cathode ray tube enables uniform electron beam cross-sections throughout the fluorescent film.
