Abstract: A capacitor includes a conductive tube, covered by insulating material and a layer of conductive material located at the central part of the tube. The geometry presents a low inherent inductance and a continuous, distributed conductance. The capacitor may be used as a bypass capacitor in an IOT amplifier to reduce stray and leakage high frequency radiation, in one amplifier being located within the inner wall of an annular input cavity.

Abstract: An electron beam tube (17) having a longitudinal axis comprises a first component, such as a ceramic wall (5) and a second component such as a drift tube assembly having a mounting plate (3). The tube further comprises means, such as member (18), arranged to allow relative sliding movement of the first component relative to the second component in a radial direction. The invention helps to alleviate mechanical stresses caused by differential thermal expansion of the components.

Abstract: The invention relates to a cathode ray tube having an input resonator cavity which includes a first metal wall (2) and, spaced apart therefrom, a second metal wall (3) each conveying a low electric potential and constituting coupling areas (6, 7) at axially spaced locations, in which areas metal elements (10, 12) conveying a high electric potential are located opposite surface sections (8, 9 and 14, 15) which are electrically connected to the metal walls (2, 3) via insulating dielectrics (11, 13), the coupling areas (6, 7) being separated by a spacing dielectric. A high-voltage stable arrangement which is resistant to temperature fluctuations is obtained in that the spacing dielectric consists of a different material than the insulating dielectrics (6, 7) and has a lower value of the product of loss factor and dielectric constant (tg.delta..times..epsilon.) at a high frequency.

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.

Abstract: In a multistage collector used in a linear beam tube such as an IOT or klystron, electrode stages are separated by ceramic rings having metallised surfaces to provide distributed bypass capacitors. This eliminates or reduces leakage or any radio frequency energy from the interior of the collector to the outside.
