Abstract
1,005,358. Cathode-ray tubes. RADIO CORPORATION OF AMERICA. Oct. 30, 1962 [Nov. 20, 1961], No. 41032/62. Heading H1D. The electron stream from the cathode of a CRT passes through a central electrode cup 22 having an apertured plate 56 with concentric openings 64, 66. The electron streams are focused by electrostatic fields to a common crossover point 74 which is imaged on the luminescent screen 19 by a further focusing means (not shown).
