Abstract
PURPOSE: To enable the cathode ray tube having excellent f ocus performance, by obtaining the electron beam accelerating electric field from the high voltage side thru the enlargement of the hole diameter of the grid G2 electrode of the cathode ray tube electron gun and by obtaining the most suitable focus voltage from small to large current region.
