    摘要： An electron gun for a television camera tube comprises a cathode for emission of electrons, a first grid disposed subsequently to the cathode and having a first aperture supplied with a positive voltage relative to the cathode, a second grid disposed subsequently to the first grid and having a second aperture supplied with a higher positive voltage than that supplied to the first grid, and an intermediate grid interposed between the first and second grids and having a hole. The intermediate grid forms a divergent electron lens near the first aperture between the first and second grids. An electron beam having passed through the first aperture is once diverged by the divergent electron lens to form a crossover at an axial position of the gun which is remote from the first grid and at which the potential on the beam axis is high, whereby broadening of the width of the velocity distribution of extracted electrons can be suppressed to a minimum and the amount of beam current passing through the second aperture can be increased.

    摘要： A camera tube device for use in a television camera comprises an electron gun including a cathode electrode for emission of an electron beam, and first and second grid electrodes respectively having apertures for controlling the diameter of the electron beam. The aperture of the second grid electrode is sufficiently smaller than the aperture of the first grid electrode. The first grid electrode is applied with a positive voltage relative to the cathode electrode and the second grid electrode is applied with a positive voltage relative to the cathode electrode which is higher than that applied to the first grid electrode. The positive voltage applied to the first grid electrode has such a value that forms the electron beam having passed through the aperture of the first grid electrode into a laminar flow beam. As the level of brightness of the object increases, the positive voltage applied to the first grid electrode is decreased to increase the amount of electron beam passing through the aperture of the second grid electrode.

    摘要： An electron gun is disclosed which includes a thermionic cathode for emitting an electron beam, a grid having a first aperture for controlling the diameter of the electron beam, and an anode having a second aperture for catching a part of the electron beam having passed through the first aperture; and in which the diameter of the first aperture is smaller than or equal to the diameter of the second aperture, and the grid and the anode are applied with positive potentials relative to a cathode potential, for example, with a voltage of 5 to tens of volts and a voltage of 100 to 500 volts, respectively, to form a uniform axial field between the grid and the anode, thereby generating a laminar flow electron beam having a constant current density.
