Embodiment 1

[0043] Such as figure 1 As shown, there is at least one second adjustable short circuit 24 , and when there is one second adjustable short circuit 24 , the second adjustable short circuit 24 is arranged coaxially with the first adjustable short circuit 23 . This arrangement makes the area of ​​the short-circuit surface 21 of the first adjustable short circuit 23 larger than the area of ​​the short-circuit surface 21 of the second adjustable short circuit 24, so that the first adjustable short circuit 23 is used as a coarse adjustment structure to roughly adjust the phase of the microwave , and the second adjustable short circuit 24 is used as a fine-tuning structure to fine-tune the phase of the microwave. Such setting greatly increases the adjustment accuracy of the phase of the microwave, and facilitates the adjustment of the phase of the microwave.

[0044] Such as figure 1 As shown, the waveguide structure 10 includes a square waveguide 11 and a circular waveguide 12 , o...

Embodiment 2

[0050] The difference from Embodiment 1 is that the number of the second adjustable short circuit breakers 24 is different.

[0051] In this embodiment, when there are multiple second adjustable short circuits 24 , the multiple second adjustable short circuits 24 are arranged in the first adjustable short circuit 23 at intervals. The arrangement of multiple second adjustable short-circuiters 24 can further increase the adjustment accuracy of the microwave phase, facilitate the control of the microwave phase, and greatly improve the phase control accuracy.

Embodiment 3

[0053] The difference from Embodiment 1 is that it also has a third adjustable short circuit.

[0054] In this embodiment, the second adjustable short circuit 24 is a cylindrical structure, the adjustable short circuit structure 20 also includes a third adjustable short circuit, the third adjustable short circuit is columnar, and the third adjustable short circuit is arranged at the second In the second adjustable short circuit 24, the end face of the third adjustable short circuit close to the entrance of the waveguide structure 10 is used as the short circuit surface 21, the third adjustable short circuit and the second adjustable short circuit 24, the first adjustable short circuit 23 is arranged coaxially, and the outer peripheral surface of the third adjustable short circuit has a choke structure 22 . Such setting further increases the adjustment accuracy of the microwave phase, facilitates the control of the microwave phase, and greatly improves the phase control accurac...

Abstract

The invention provides a microwave short-circuiter. The microwave short-circuiter includes: a waveguide structure; and an adjustable short-circuit structure which is movably connected with the waveguide structure, wherein at least one part of the adjustable short-circuit structure is located in the waveguide structure, the adjustable short-circuit structure moves in the axial direction of the waveguide structure, the adjustable short-circuit structure is provided with at least two mutually independent short-circuit surfaces, and the short-circuit surfaces are movably arranged in the waveguide structure. The problem that in the prior art, a microwave short-circuiter is poor in phase adjustment precision is solved.

Description

technical field [0001] The present invention relates to the technical field of microwave equipment, in particular to a microwave circuit breaker. Background technique [0002] With the development of science and technology, the application fields of electron linear accelerators are becoming more and more extensive, such as medical electron linear accelerators, irradiation electron linear accelerators, non-destructive testing accelerators and accelerators for scientific research. Different situations have different requirements for accelerator energy. For example, medical accelerators need to choose different energy rays for treatment according to different tumors in different parts; irradiation accelerators need to choose different energy rays for irradiation according to the penetration depth of different goods; non-destructive testing accelerators also According to the thickness of different workpieces, the radiation with the corresponding energy gear should be selected fo...
