MICROWAVE GENERATOR WITH VIRTUAL CATHODE OF COAXIAL TYPE Russian patent published in 2014 - IPC H01J25/02 

FIELD: electricity.

SUBSTANCE: invention can be used for generation of high-power pulses of electromagnetic emission with high-current electron beams. A microwave generator with a virtual cathode of coaxial type includes high voltage source (1), the negative electrode of which is connected to earthed cylindrical vacuum chamber (2), high-voltage insulator (3) installed in the end face of the chamber, cylindrical grid anode (7) located along the chamber axis and connected to positive electrode (9) of high voltage source (1) through anode holder (8) and high voltage insulator (3), a cathode assembly with cylindrical cathode (11), which is located inside anode (7) on its axis and connected to vacuum chamber (2) through coaxial conical line (4), which is connected with a wide end to a free end face of chamber (2) and with a narrow end to coaxial waveguide junction (5), to which antenna (6) and matching element (14) are connected.

EFFECT: enlarging functional capabilities; improving reliability of the device.
