摘要： A tetrode (four electrode) gun (202) is described which allows the adjustment of both variable high brightness and illumination uniformity in the profile of the electron beam. This is achieved by providing an electrostatic focusing electrode (18) between the cathode (2) and the anode (8) within the electron gun. The focusing electrode is positively biased to a few keV and allows the image of the cathode to be focused at infinity. The addition of a focusing electrode enables both variable brightness and illumination uniformity by adjustment of the bias of a grid (4) which is mounted below the cathode to maintain constant emission, while adjusting the bias of the focusing electrode to obtain the optimal beam cross-sectional uniformity.

摘要： In a cathode ray tube provided with a limiting aperture (LA) in an electron gun, the axial potential between the limiting aperture (LA) and an electrode (SG) arranged at the rear stage of the limiting aperture (LA) is lower than a potential of the limiting aperture (LA) by several tens of volts, so that secondary electrons generated from the limiting aperture (LA) are hindered from reaching a fluorescent screen (1) or a target screen of the cathode ray tube.

摘要： A gun for a linear-beam electron tube has a control grid (40) for modulating the beam current which consists of an array of conductive web elements (50, 52) whose spacing from each other is much larger than their spacing from the concave emissive surface (31) of the cathode (30). It was found that when this condition is met, the grid (40) can be operated at cathode potential while beam current is being drawn without distorting the electric accelerating field enough to ruin the focusing of the beam. Thus, when the grid (40) is used to pulse the beam current on and off, it can have zero bias in the "on" condition, whereby the pulse modulator can be greatly simplified.
摘要翻译：用于线性束电子管的枪具有用于调制射束电流的控制栅格（40），该控制栅格由导电纤维网元件（50,52）的阵列组成，所述导电纤维网元件（50,52）的距离远大于它们与凹面发射（30）的表面（31）。已经发现，当满足这个条件时，可以在阴极电势下操作栅极（40），同时汲取电子束电流而不扭曲电加速场足以破坏光束的聚焦。因此，当电网（40）用于脉冲打开和关闭射束电流时，它可以在“开启”状态下具有零偏压，由此可以大大简化脉冲调制器。

摘要： Electron-optical device having two elongate emitting regions arranged symmetrically with respect to a longitudinal axis for producing two electron beams having an elongate cross section. By means of electron grids, the two beams are focused at the same point of an electron target arranged transversely to the longitudinal axis and having a short central axis and a long central axis. The elongate emitting regions have their smallest cross section parallel to the scanning direction of a device, cooperating with the electron-optical device, for scanning a target arranged transversely to the longitudinal axis.

摘要： One embodiment relates to an electron beam apparatus which includes a dual-lens electron gun for emitting an electron beam. The electron beam is a high beam-current electron beam in a first operating mode and a low beam-current electron beam in a second operating mode. The apparatus further includes a column aperture which is out of the path of the high beam-current electron beam in the first operating mode and is centered about an optical axis of the electron beam apparatus in the second operating mode. Another embodiment relates to an electron gun which includes a first gun lens, a beam limiting aperture, and a second gun lens. The first gun lens focuses the electrons before they pass through the beam-limiting aperture while the second gun lens focuses the electrons after they pass through the beam-limiting aperture. Other embodiments, aspects and features are also disclosed.

During the emission of electrons from the emitter (6), the relationships are satisfied: 10 [V/ mu m] > (Va-Vg) / (Ha-Hg) > Vg / VaVg / Hg [V/ mu m] > VaX10 X (9.7-1.3 X ln(Hg)) X (1000/Ha) where Ha [ mu m] is the distance between the anode and emitter, Va [V] is the voltage between the anode and emitter, Hg [ mu m] the distance between the gate and emitter, and Vg [ mu m] is the voltage between the gate and emitter.
