Abstract: A device for achieving a narrow high voltage output pulse having a rise t essentially limited only by the rise time of the switching means.

Abstract: A typical embodiment of the invention is a multiple electron beam device 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 diode target array which then generates a coded digital output signal that corresponds to the analog input.

Abstract: A combined pulse modulated laser in which a modulated cold cathode device is utilized to excite a combined electron beam bombarded semiconductor device grown integrally with a crystal laser to achieve modulation of the laser output with fast rise and fall times under low voltage and high current conditions.
