Gyrotron energy coupling window

Abstract

The embodiment of the invention provides a gyrotron energy coupling window. The gyrotron energy coupling window comprises a window support cylinder, a window positioning flange adapter plate, a windowsealing cylinder and cooling water joints, wherein the window support cylinder is arranged at the bottom of the window sealing cylinder, the window positioning flange adapter plate is connected to the window positioning flange adapter plate in a sleeving mode, and the window support cylinder, the window sealing cylinder and the window positioning flange adapter plate are welded in an airtight mode; and at least two cooling water joints communicated with the interior of the window positioning flange adapter plate are further arranged on an outer side of the window positioning flange adapter plate. The gyrotron energy coupling window overcomes the problems that in the prior art, when a gyrotron works at high power and continuous waves, due to electron energy consumption, a large amount of heat energy is deposited on a cavity wall and an energy coupling window, the temperature of a window piece is too high, the thermal stress is too large, the output power, the mode purity and the stability of the gyrotron are reduced, and the gyrotron is scrapped due to the fact that the window piece is broken under severe conditions.

Description

technical field [0001] The invention relates to the technical field of gyrotron manufacture, in particular to an energy coupling window of a gyrotron. Background technique [0002] Terahertz science and technology is an interdisciplinary emerging interdisciplinary science, connecting the macroscopic classical electromagnetic wave theory and the microscopic quantum theory. Terahertz waves have unique characteristics such as transient, high penetration, broadband, coherence and low energy. Feature analysis, material detection and other fields have broad application prospects. [0003] Since 2000, terahertz vacuum electronics has developed rapidly and achieved important results. The high-power terahertz sources of vacuum electronics that can work in the terahertz frequency band mainly include gyrotrons, SmithPurcell effect devices, return wave tube etc. Among these devices, the gyrotron is a fast-wave device. Compared with other devices, the size of the high-frequency struct...

AI Technical Summary

Problems solved by technology

[0005] When the gyrotron in the prior art works at high power and continuous wave, a large amount of heat energy is deposited on the cavity wall and the energy coupling window due to the energy consumption of electrons, which will cause the temperature of the window to be too high and the thermal stress to be too large, thereby reducing the gyrotron The output power, mode purity and stability of the tube, in severe cases will cause the window to break and cause the gyrotron to be scrapped
