VIRCATOR Russian patent published in 1998 - IPC

FIELD: high-power microwave engineering; microwave oscillators. SUBSTANCE: vircator has power supply, cathode electrode, anode electrode, and beam output channel with window all axially arranged in cylindrical drift tube; flat part of anode electrode is made in the form of diaphragm mounted in parallel with end surface of cathode which has annular drilling on end surface; anode is electrically coupled with diaphragm through hollow conducting cylinder arranged on diaphragm coaxially to cathode in its annular drilling in a spaced relation relative to cathode; diaphragm has axial hole whose diameter is smaller than or equal to that of cylinder. EFFECT: improved efficiency of generated beam. 1 dwg
