Abstract

The invention discloses a high-power microwave load, which comprises a body, a wedge plug, absorption sheets, water inlet pipes and water outlet pipes. The body is a cuboid with a waveguide cavity. One side wall of the body is provided with a plurality of V-shaped grooves arranged side by side in the length direction of the cuboid; and one side wall of the body is provided with a plurality of first water passing holes in the width direction of the cuboid. The wedge plug comprises a side plate corresponding to the end surface of the body and a plurality of wedge-shaped parts. One end of each ofthe plurality of wedge-shaped parts is connected to the side plate, and is matched with and corresponding to each of the plurality of V-shaped grooves. The side surface of each wedge-shaped part is provided with a plurality of second water passing holes. The absorption sheets comprise a first absorption sheet and a second absorption sheet, which are fixed to the inner surfaces of the waveguide cavity respectively, and a third absorption sheet and a fourth absorption sheet, which are fixed to the surfaces at the two sides of the plurality of wedge-shaped parts. The water inlet pipes and the water outlet pipes are fixedly arranged at the two sides of the body and the wedge-shaped parts respectively and are communicated with the two ends of the first water passing holes and the second waterpassing holes correspondingly.

Description

technical field [0001] The invention relates to the field of microwave technology. More specifically, it relates to a high power microwave load. Background technique [0002] The microwave load is one of the important components in the microwave circuit. Its main function is to absorb all the microwave power without reflection. The principle is generally to use the medium to absorb the remaining power of the system to form a matching state without reflection at the terminal. In accelerator systems, high-power loads are often required to absorb radio frequency power, and the development of high-power loads has always been one of the research hotspots in the accelerator field. [0003] According to different structures, the load can be divided into surface absorption matching load and volume absorption matching load. Surface absorption loads are often used in low power applications, and body absorption matching loads are often used for high power. Body absorption load can b...
