    摘要: A system for regulating beam current in a cathode ray tube. The system includes test signal timing and pulse generation logic for outputting test signals operable to stimulate a cathode ray tube at two voltage levels. The system further includes a circuit that inputs the test signal timing and determines correction signals based on signals derived from the cathode in response to stimulating the cathode ray tube at the two voltage levels. The correction signals may include a gain correction signal, a bias correction signal or both. The gain correction signal modifies a signal output to a gain driver that may be AC coupled to the cathode. The bias correction signal output to a clamping circuit coupled to the cathode.

    摘要: A linear beam device comprises a cathode and an anode spaced therefrom, with the anode and cathode being operable to form and accelerate an electron beam. An RF interaction region having a drift tube is arranged relative to the anode to permit the electron beam to pass therethrough. A multi-stage depressed collector of the linear beam device has a plurality of collector electrodes successively arranged to collect spent electrons of the electron beam after passing through the RF interaction region. Each one of the plurality of collector electrodes has a distinct voltage level applied thereto defining a decelerating electric field within the collector. At least one of the plurality of collector electrodes further comprises a collecting surface having a shape that is normal to a coincident trajectory of the spent electrons, whereby a substantial portion of the collecting surface is covered with a plurality of narrow grooves. In an embodiment of the invention, the grooved collector electrode further comprises the final electrode of the collector. The final electrode has a surface that is substantially spherical, and the plurality of grooves may be arranged in a concentric pattern of circles on the electrode surface. The plurality of grooves may be formed to a depth that is approximately twice a corresponding width. A region adjacent to an opening of each of the plurality of grooves comprises electric fields defining a convergent lens, thereby focusing the spent electrons into the plurality of grooves.

    摘要: A main lens of an electron gun assembly comprises a sixth grid, a seventh grid, an eighth grid, and a ninth grid. An asymmetric lens section is created between a fifth grid and the sixth grid on a cathode side of the main lens. The asymmetric lens section has such asymmetry that lens functions of the asymmetric lens section acting on the electron beams are different between the horizontal direction and the vertical direction, and has a lens power varying in synchronism with the deflection of the electron beams. In this asymmetric lens, the asymmetry for a center beam differs from that for side beams.

The electron gun also includes a voltage-dividing resistor for producing a voltage applied to a first focus electrode by dividing a voltage applied to the anode, and a metal conductor surrounding the resistor and fixed to a second focus electrode upstream of the first focus electrode. The resistor is disposed in the vicinity of one of the support rods, is formed of an insulating film, a resistance pattern, and a substrate disposed in the order named from the insulating film toward the neck portion. The resistance pattern is such that a potential difference between the metal conductor and a portion of the resistance pattern facing the metal conductor is equal to or smaller than 4 kV.
