Abstract : A typical embodiment of the invention is a multiple electron beam device for converting analog input signals into coded digital output signals. A beam of electrons, generated through a Watkins-Johnson laminar flow sheet beam electron gun is focused before being divided into eight individual beams by means of an eight section traveling wave time deflection system. The individual beams then are controlled by means of a traveling wave analog deflection system before they pass through an apertured target structure that corresponds to the digital code. The beams traveling through this target impact on a diodde target array which then generates a coded digital output signal that corresponds to the analog input. (Author)
