Title:
ELECTRON GUN AND VACUUM ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/236785
Kind Code:
A1
Abstract:
The present application provides an electron gun and a vacuum electronic device.
According to the present application, the anode and the signal input system of the electron gun are integrated to achieve the integrated design and manufacturing of the electron gun and the signal input system. Meanwhile, the length of the circuit for energy exchange between an electron beam and a high-frequency circuit is shortened, and the energy exchange efficiency between the electron beam and a high-frequency circuit can be improved. The electron gun comprises a cathode, a focusing electrode and an energy exchange module, wherein the energy exchange module comprises an anode port, a signal input port and an energy exchange unit. The input signal is input into the energy exchange unit from the signal input port, and the electron beam is transmitted from the anode port to the energy exchange unit for energy exchange with the input signal. The electron beam is formed by means of the cathode, the focusing electrode and the anode port.
