Abstract

1,169,725. Electron beam apparatus. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 30 Nov., 1966 [3 Dec., 1965], No. 53557/66. Heading E1D. An electron gun for use in a CRT comprises a cathode 1 with an emissive area 2 less than 0.35 mm.<SP>2</SP>, a control electrode 3 having an opening 8, 1.4 to 2À6 times the emissive area and approximately 100 microns from the cathode surface, a first anode 4, two acceleration electrodes 5, 7 and a focusing electrode 6. The emissive area may be circular, elliptical or oval.
