Acceleration device and medium laser accelerating structure based on semiconductor laser

Abstract

The invention discloses an acceleration device, which comprises a first electrode and a second electrode, wherein the first electrode and the second electrode are oppositely arranged; a first waveguide layer and a second waveguide layer, wherein the first waveguide layer is located under the first electrode and the second waveguide layer is located on the second electrode; an active region locatedbetween the first waveguide layer and the second waveguide layer; a blazed grating; a reflecting layer, wherein the reflecting layer and the blazed grating are located between the first electrode andthe second electrode and are vertically arranged on the two sides of the first electrode and the two sides of the second electrode respectively; an electron beam channel, wherein a grating is formedon at least one side of the electron beam channel to serve as an acceleration area; and a vacuum region which is a region surrounded by the end surface of the active region, the blazed grating and thesemiconductor material. According to the acceleration device, particles can be directly and conveniently accelerated through ingenious arrangement of the active region, the blazed grating and the reflecting layer, other external complex light paths do not need to be additionally built, and the acceleration device is small and exquisite in structure, simple and effective.

Description

technical field [0001] The invention relates to the technical field of particle acceleration, in particular to an acceleration device and a dielectric laser acceleration structure based on a semiconductor laser. Background technique [0002] With the development of modern science and technology, human beings have a deeper and deeper understanding of the composition of matter, but exploring the material world at different levels requires the use of different detection tools, and particle accelerators are one of the important tools for human beings to explore the microscopic world. At present, high-energy accelerators are very large in size and expensive to build. Taking other accelerator devices that generate hard X-rays as an example, the total budget usually exceeds US$1 billion, and the size of the device is measured in kilometers. With the development of science and technology, many fields have put forward high gradient and portability requirements for accelerators. Ther...
