characters and symbols that could be formed. The beam, which then had the cross-section of the desired character, was re-centered along the axis of the tube and deflected to the desired position of the screen for display. Alternately, as in the accompanying image, the entire matrix was filled with the electron beam then deflected through a selection aperture to isolate one character.
135:
The
Charactron CRT used an electron beam to flood a specially patterned perforated anode that contained the stencil patterns for each of the characters that it could form. The first deflection positioning of the electron beam steered the beam to pass through one of the (typically 64 or 116)
166:
camera for recording of computer generated data. The
Stromberg-Carlson SC-4000 series system was a typical use of the 5-inch-diameter (130 mm) tube

which generates an electrical signal by scanning an electron beam of uniform cross section across a printed pattern on an internal target electrode.
