Cathodoluminescent gas discharge device with improved modulation characteristics

摘要: A cathodoluminescent gas discharge device having improved modulation characteristics whereby an electron beam generated by the is more easily modulated a small control voltage. The includes cathode for generating to be used as source of electrons. An electron-transmissive extraction grid spaced from and receives electrical potential extracting electrons discharge. voltage modulating flow through itself. "drift space" length approximately equivalent at least one ionization mean free path located between either electrode or in order lower energy arriving so that therethrough can smaller amplitude than possible without drift space. target anode accelerating toward itself those which pass grid. spacing chosen too small, pressure within device, sustain therebetween.
