Abstract
The present invention is directed to an electron beam crossbar switch for interconnection between communication units. The crossbar switch includes an array of electrically charged particle emitter source devices with an input connected to a slow wave structure coupled to the emitter source. An array of detectors is positioned relative to the array of emitter devices for receiving charged particles from various of the emitter devices. X and y deflection means are positioned adjacent each of the emitters for directing the charged particles from each of the emitters to at least one of the detectors to provide more signal output and a reduction in deflection accuracy.
