Abstract

PURPOSE:To prevent the increase of capacitive residual image due to the speed dispersion by making the electron beam into layer stream state thereby reducing the repulse between the electrons. CONSTITUTION:Planar or cup shaped first and second grids G1, G2 having a cathode K and apertures h1, h2 and an anode having a limiting aperture a are provided. The diameter phi1 of the aperture h1 in first grid G1 is selected smaller than 0.6mm. while the diameter phi2 of the aperture h2 in second grid G2 is made smaller than phi1, and the distance d01 between the cathode K and first grid G1 is selected to be 0.06-0.20mm. while the distance d12 between first grid G1 and second grid G2 are selected to be 0.06-1.2mm..
