摘要： A novel photocathode employing a conduction band barrier is described. Incorporation of a barrier optimizes a trade-off between photoelectron transport efficiency and photoelectron escape probability. The barrier energy is designed to achieve a net increase in photocathode sensitivity over a specific operational temperature range.

摘要： An electron gun for generating an electron beam is provided, which includes a secondary emitter. The secondary emitter includes a non-contaminating negative-electron-affinity (NEA) material and emitting surface. The gun includes an accelerating region which accelerates the secondaries from the emitting surface. The secondaries are emitted in response to a primary beam generated external to the accelerating region. The accelerating region may include a superconducting radio frequency (RF) cavity, and the gun may be operated in a continuous wave (CW) mode. The secondary emitter includes hydrogenated diamond. A uniform electrically conductive layer is superposed on the emitter to replenish the extracted current, preventing charging of the emitter. An encapsulated secondary emission enhanced cathode device, useful in a superconducting RF cavity, includes a housing for maintaining vacuum, a cathode, e.g., a photocathode, and the non-contaminating NEA secondary emitter with the uniform electrically conductive layer superposed thereon.

摘要： A scanning reflection electron diffraction microscope causes a primary electron beam from its electron gun to be reflectively diffracted from a sample and a diffraction pattern to be formed on a fluorescent screen. An optical lens reduces this diffraction pattern in size and forms its reduced image on a photoelectric surface, thereby producing an image-carrying electron beam. Deflected by a deflecting system including a deflecting coil and a condenser coil, the image-carrying electron beam is detected by an electron-multiplier such that a diffraction pattern is displayed on a cathode ray tube.

摘要： An improved electron discharge device comprises an evacuated envelope having at least one alumina ceramic insulator member. Within the device is a source of electrons, and an electron multiplier assembly including an anode. A high resistance material is diffused into the ceramic insulator to reduce luminescence within the insulator. The method of diffusion includes the steps of applying an opaque coating of a high resistance material to a surface of the ceramic insulator member and then firing the member in a reducing atmosphere at a temperature within the range of about 1500.degree. C. to 1550.degree. C. until the high resistance material diffuses into the surface of the member forming a diffusion region.

摘要： The image contrast in an image display tube having a channel plate electron multiplier (2) is improved by preventing secondary electrons emitted from the face of an input dynode (26) from straying to channels located at a relatively large distance from their origin. This is done by disposing a grid (24) at a short distance from the input dynode (26). If the grid (24) is held at a positive voltage relative to the input dynode (26), stray secondary electrons will be attracted toward the grid (24). Alternatively, if the grid (24) is held at a negative voltage relative to that of the input dynode (26), the secondary electrons will be induced to enter channels close to their origin.
摘要翻译：具有通道板电子倍增器（2）的图像显示管中的图像对比度通过防止从输入倍增极（26）的面发射的二次电子偏离位于与其原点相对较大距离的通道而被改善。这通过在与输入的倍增电极（26）短距离处布置网格（24）来完成。如果电网（24）相对于输入的倍增电极（26）保持在正电压，则杂散二次电子将被吸引到电网（24）。或者，如果电网（24）相对于输入的倍增电极（26）的电压保持在负电压，则二次电子将被诱导进入接近其原点的通道。

摘要： An image display device includes at least one display cell having the following in spaced relation: a photocathode; multiplier dynodes, an anode electrode; and a cathodoluminescent screen. In addition to an optical feedback fluorescent material, the anode electrode includes a material which exhibits slow fluorescence, e.g., Y.sub.2 O.sub.3 :Gd3%, such that it emits light energy for a finite time period after it has been excited by electrons. In the operation of the display device, an electrical discharge is employed to produce the desired optical output at the cathodoluminescent screen. Some of the electrons created in the discharge strike the anode electrode, causing light energy to be directed to the photocathode where it is converted into free electrons. The presence of these free electrons ensures the rapid initiation of subsequent electrical discharges. In other embodiments, the electrical discharge may be obtained through ion feedback or plasma discharge.
摘要翻译：图像显示装置包括具有以下间隔关系的至少一个显示单元：光电阴极; 乘法器倍增电极，阳极电极; 和阴极发光屏。除了光反馈荧光材料之外，阳极电极包括显示出缓慢荧光的材料，例如Y 2 O 3：Gd 3％，使得其在被电子激发之后在有限时间段内发射光能。在显示装置的操作中，采用放电在阴极发光屏上产生期望的光输出。在放电中产生的一些电子撞击阳极电极，导致光能被引导到光电阴极，在那里被转换成自由电子。这些自由电子的存在确保随后放电的快速启动。在其他实施例中，可以通过离子反馈或等离子体放电获得放电。

摘要： The invention includes an electron tube such as an image intensifier which utilizes a channel-type electron multiplier. The multipler is made of a perforated glass plate made in a manner such that secondary emission may be produced at the interior surfaces of the holes through the plate. Primary electrons are introduced to the holes at one end and a much larger emission emanates from the other end. Conductive layers on each side of the plate have holes in registration with the plate holes. The conductive layers are maintained at potentials to accelerate electron flow through the holes. In accordance with the present invention, a third conductive layer is provided at the output side. When the third conductive layer is maintained negative, resolution is improved.
