A New High-Speed Cathode-Ray Tube
Abstract
A cathode-ray tube, DuMont type K1056, has been developed to fulfill the need for simplifying the recording of transient waveforms that require spot velocities of 3,000 in/microsecond and higher. The K1056 was developed jointly by the Vacuum Tube Division of the Allen B. DuMont Laboratories, Inc., and the Naval Research Laboratory. The evolution of the K1056 design required consideration of such design parameters as tube-envelope dimensions, electrode connections, deflection-plate configuration, screen-phosphor type, screen thickness, and sizes and spacings of beam-forming elements. The effects of spurious screen illumination and transit time were determined experimentally. Full information on the characteristics (operating voltages, inter-electrode capacitances, etc.) is presented. Typical operating voltages are 7.5 kilovolts on the second anode and 30 kilovolts on anode three.
