摘要： The invention relates to the field of production of barium-scandate dispenser cathodes or other barium-scandate materials. A target (66) containing a mixture of BaO, CaO, Al2O3 and Sc2O3 tends to be more stable, the higher the scandia (scandium oxide) content is. However, an increased scandia content results in a reduced emission capability. A destabilizing effect of BaO and CaO reactions is counteracted by the more inert Sc2O3 and also Al2O3 components, as not only an increased scandia content stabilizes the material but also an increased alumina (aluminum oxide) content improves the stability.

摘要： A system which integrates "intelligent" electronic feedback into the structure of vacuum electronic devices whose subcomponents are electronically and/or electro-mechanically adaptive. By "vacuum electronic device," is meant any source of microwave (or millimeter-wave) power generation which is driven by electron beams. Such a device is divided into the following main subsections: an electron emitter, an electron beam shaping & acceleration region, an rf signal input coupler (for amplifiers), an electron-beam drift region, at least one rf/beam interaction region where beam energy is converted to an rf signal, a beam-dump region, and the rf signal output coupler. Some of those subsections are instrumented with electronic sensors. The data collected by those sensors will feed into an "on-board" microcomputer (logic unit subsection 8) which will compare it to "ideal" set of values for those parameters. The microcomputer will then "decide" what if any changes to make to a given set of electrically (or electro-mechanically) adjustable operating conditions in certain subsections of the device, and adjust the rf output signal towards a set of ideal characteristics that are predetermined by users of the system.

摘要： The invention provides a travelling wave tube having a directly heated cathode. Cathode material is applied in a depression in one U-shaped member of a high resistance alloy material and the return path for heater current is provided by another U-shaped strip member beneath the first. The configurations of the two strip members are similar so that stray magnetic fields generated by the equal but opposite currents flowing therein, tend to neutralize one another. In another embodiment the two strip members are replaced by generally cylindrical members, one member being within the other. The surface of the member providing the return path for heater current is polished where it faces the member carrying the cathode material so as to reflect back heat radiated by the last-mentioned member.
