专利汇可以提供Field effect electron gun having at least a million emitting fibers per square centimeter专利检索，专利查询，专利分析的服务。并且An electron gun uses a field effect emitter in a vacuum tube, providing the advantages of cold cathode emission at atmospheric temperature in addition to a simplified control system. Temperature independent emission is achieved by using an oxidemetal composite emitter for releasing electrons. The anode and emitter can be shaped to produce a desirable electric field and current path for special electron tubes.，下面是Field effect electron gun having at least a million emitting fibers per square centimeter专利的具体信息内容。

权利要求

1. An improved electron gun assembly for use in evacuated electron tubes and comprising: a field effect emitter having a planar emitting surface for emitting electrons in a vacuum at prevailing ambient temperatures, said emitter having at least a million emitting fibers disposed in parallel per square centimeter of emitting surface; a conductive backing plate adjoining respective first ends of said fibers for conducting an electrical potential thereto; an insulating oxide matrix encompassing separating said fibers, respective second ends of said fibers terminating in said emitting surface below the surface plane of said oxide; and a flat surfaced, shaped accelerating anode the surface of said oxide matrix and in parallel spaced apart relationship for enhancing electron flow from said emitter, said anode and said emitter having circular surfaces and said anode further having an apertured center for providing a hollow electron beam when subjected to an electric field.
