摘要： A hollow cylindrical member composed of a high-voltage potting material is secured adjacent the photocathode to the high-voltage potting material encircling the image-tube. The hollow member is concentric with the axis of the tube and extends away from the photocathode. A plurality of equally spaced metallic discs are embedded in the potting material of the corona-shield interconnected by a plurality of resistors. A high-voltage is coupled to one of the metallic discs adjacent the photocathode and a ground is coupled to another of the metallic discs most remote from the photocathode.

摘要： A write electron gun is disposed at one end of a vacuum envelope to produce an electron beam modulated by an external input signal having signal elements occurring at a first given rate. A self-scanned array is disposed at the other end of the envelope. An electron beam deflection system is disposed in the envelope between the electron gun and the array to scan the electron beam over the array to store the signal elements in the array with the array providing electron gain for the stored signal elements. A source of read out signals is disposed externally of the envelope coupled to the array to read out the signal elements at a second given rate less than the first given rate.

摘要： A dynode assembly having a given length and a field electrode assembly having the same given length are disposed in a vacuum envelope. The dynode assembly is in a first plane parallel to and spaced from the longitudinal axis of the envelope and the field electrode assembly is disposed in a second plane parallel to and spaced from the axis in a direction opposite to the spacing of the dynode assembly. The dynode assembly receives on its input end input electrons produced by an input signal which may be either electrical or optical. The field electrode assembly is shifted along the axis with respect to the dynode assembly such that the output end of the field electrode assembly extends beyond the output end of the dynode assembly such that lines of equal potential between the two assemblies form an angle .theta. with the first and second planes. A first operating voltage is coupled to both assemblies adjacent the input end thereof and a second operating voltage is coupled to both assemblies adjacent the output ends thereof. The second operating voltage has a value which is greater and more positive than the value of the first operating voltage. A bias voltage electrode having a bias voltage coupled thereto is disposed in the envelope adjacent the input end of both of the assemblies at an angle .theta. with respect to the first and second planes to ensure that all of the electrons are directed between the two assemblies. A collector electrode having an accelerating voltage coupled thereto is disposed in the envelope adjacent the output end of both assemblies at an angle .theta. with respect to the first and second planes. The collector electrode provides a multiplied output current for the multiplier.
