Abstract
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 b…
