ABSTRACT:
A thin kinescope has the electron gun positioned to emit electrons so that the initial direction of travel is substantially parallel to the plane of the screen. A bowl-shaped reflector is positioned to bend the electron beams toward the screen and to improve the focusing of the electron beams. A unique combination of deflection enhancement and a shunted quadrupole result in maximum deflection so that the entire screen is scanned by the electron beams.
