Double-electron-beam relativistic backward wave tube with radial structure

Abstract

The invention relates to a double-electron-beam relativistic backward wave tube with a radial structure, and aims to solve the technical problem that related devices of an existing relativistic backward wave tube are difficult to meet higher and higher output power requirements on high-power microwave devices at present. According to the invention, an upper anode, a lower anode, a cathode of a high-voltage diode structure, an upper guide magnetic field generation device and a lower guide magnetic field generation device are utilized to form a double-electron-beam relativistic backward wave tube of a radial structure, and the backward wave tube is of an up-down mirror symmetry structure and also of a rotational symmetry structure. The upper anode and a lower anode adopt plate-shaped structures which are parallel to each other and are arranged in a mirror symmetry manner, a gap between the upper anode and the lower anode serves as an electron beam-electromagnetic wave channel a, a double-electron-beam working mode that a cathode of a high-voltage diode structure generates two relativistic electron beams which are transmitted in the radial direction is adopted, compared with a single electron beam, the double-electron-beam cathode can double the generated current by doubling the injection wave power of the backward wave tube, so that the output power of the backward wave tube is improved.

Description

technical field [0001] The invention relates to a relativistic return wave tube, in particular to a relativistic return wave tube with a radial structure and double electron beams. Background technique [0002] The relativistic return wave tube is a very potential high-power microwave device. The research on the relativistic return wave tube at home and abroad is mainly focused on improving work efficiency, using low magnetic field conditions, and increasing the output power of the relativistic return wave tube. Among them Output power and working efficiency have always been important indicators in the development of relativistic return wave tubes, and are also one of the important advantages of relativistic return wave tubes over other high-power microwave devices. For the output power, researchers usually use hybrid structures and non-uniform slow-wave structures to increase the output power of a single device (a single device is a single relativistic return wave tube, and...
