Abstract: An electron beam focusing electrode and an electron gun using the same may include a plate having a polygonal through-hole; at least a projecting portion formed on at least one side of the through-hole. By using the electron beam focusing electrode, a spreading phenomenon of an electron beam having a rectangular cross section may be reduced. Further, the output of the electron gun may be increased, and electron beams may be easily focused.

Abstract: Techniques disclosed herein include apparatus and processes for generating a plasma having a uniform electron density across an electrode used to generate the plasma. An upper electrode (hot electrode), of a capacitively coupled plasma system can include structural features configured to assist in generating the uniform plasma. Such structural features define a surface shape, on a surface that faces the plasma. Such structural features can include a set of concentric rings having an approximately rectangular cross section, and protruding from the surface of the upper electrode. Such structural features can also include nested elongated protrusions having a cross-sectional size and shape, with spacing of the protrusions selected to result in a system that generates a uniform density plasma.

Abstract: Since the accumulation regions fd1, fd2 are connected only to a single capacitor C1, a pixel can be decreased in size to improve spatial resolution. And, charges transferred into the accumulation regions fd1, fd2 are temporarily accumulated, thereby improving a signal-noise ratio. The driving circuit DRV conducts dummy switching so that the number of switching of the first switch Φ1 is equal to the number of switching of the second switch Φ2 after termination of the reset period within one cycle, thus making it possible to cancel offset and obtain a more accurate range image.

Abstract translation: 由于累积区域fd1，fd2仅与单个电容器C1相连，因此能够减小像素以提高空间分辨率。 并且，暂时累积转移到累积区域fd1，fd2的电荷，从而提高信噪比。 驱动电路DRV进行虚拟切换，使得第一开关Φ1的切换次数等于在一个周期内的复位周期结束后的第二开关Φ2的切换次数，从而可以消除偏移并获得 更准确的范围图像。

Abstract: A grid component for use with a vacuum electron device (VED), such as an inductive output tube (IOT), includes a skirt that adds structural support and aids in alignment. The grid component has a dome in which a grid pattern is formed and includes an annular, concentric flange surrounding the dome. The skirt is formed concentrically around the flange. Alignment orifices may be provided in the flange for passage of alignment pins in the assembled product. The grid, flange, and skirt are a unitary component and are formed by a chemical vapor deposition (CVD) or similar process, in which a mandrel is used to provide a deposition surface. The mandrel is placed in a furnace, and a high-temperature CVD process is used to break down a hydrocarbon gas to thereby deposit a pyrolytic graphite coating onto the mandrel. The mandrel may include a skirt template to provide the characteristic skirt.

Abstract: A field-emission electron source apparatus includes a vacuum container that receives a field-emission electron source array, a target and an auxiliary electrode, and a getter pump that is disposed in the vacuum container and absorbs and removes excess gas. An electron beam emitted from the field-emission electron source array passes through a plurality of through holes formed in the auxiliary electrode and reaches the target. A space containing the field-emission electron source array and a space containing the target and the getter pump are separated substantially by the auxiliary electrode so that gas generated from the target is absorbed by the getter pump without passing through the space containing the field-emission electron source array. This makes it possible to provide a highly-reliable field-emission electron source apparatus in which the influence of gas and ions on the field-emission electron source array is eliminated or reduced.

Abstract: A solid-state vacuum device (SSVD) and method for making the same. In one embodiment, the SSVD forms a triode device comprising a substrate having a cavity formed therein. The SSVD further comprises cathode positioned near the opening of the cavity, wherein the cathode spans over the cavity in the form of a bridge that creates an air gap between the cathode and substrate. In addition, the SSVD further comprises an anode and a grid that is positioned between the anode and cathode. Upon applying heat to the cathode, electrons are released from the cathode, passed through the grid, and received by the anode. In response to receiving the electrons, the anode produces a current. The current received by the anode is controlled by a voltage applied to the grid. Other embodiments of the present invention provide diode, tetrode, pentode, and other higher order device configurations.

Abstract: A grid for use in a linear electron beam tube such as an IOT or TWT includes a grid section and a focus electrode between which is included an accommodation portion. The grid is mounted in the tube by a mounting flange around its outer periphery. During use, the grid section becomes hot and consequently expands but the mounting flange remains relatively cool being connected to a relatively massive structure. Thin flexible strips of the accommodation section permit movement between the mounting flange and the grid section due to differential thermal expansion, thus minimising distortion to the grid section which might otherwise occur if it were connected directly to the mounting flange and hence fixed in its outer diameter length. In other embodiments, the focus electrode is omitted.
