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