Abstract

The invention discloses high-energy micro-focus X-ray production equipment, which comprises an electron source assembly used for generating high-energy electron beams and rotating target equipment used for being bombarded by the electron beams to generate high-energy X-rays, and the high-energy focused electron beams generated by the electron source assembly are bombarded to the rotating target equipment to generate high-energy micro-focus X-rays. According to the invention, a specific electron source and a linear accelerator are matched to provide the electron beam with long macro pulse and high average flow intensity, and the transverse size of the electron beam with long macro pulse and high average flow intensity is focused to a relatively small size at a targeting position through thefocusing of a solenoid and a strong focusing quadrupole lens group; and a beam spot measuring assembly is used for precisely measuring and controlling the transverse size of the electron beam, the size of the beam spot is controlled to 0.1mm or below, and the purpose of high-energy micro-focus X-ray output is achieved.

Description

technical field [0001] The invention belongs to the field of radiation devices, in particular to a high-energy micro-focus X-ray production equipment. Background technique [0002] Industrial CT (Industrial Computed Tomography), as the best non-destructive testing method, can visually display the internal structure information of objects, and can locate defects and measure spatial dimensions. It is widely used in aerospace, aviation, nuclear power, metallurgy, machinery, electronics, construction Non-destructive testing, non-destructive evaluation and reverse engineering in petrochemical and other fields. [0003] X-ray sources are the core components of industrial CT imaging, mainly low-energy micro-focus ray sources, conventional X-ray tube ray sources and traditional high-energy accelerator ray sources. The electron beam is used to accelerate the target in an electric field, and the bremsstrahlung is converted into X-rays. Low-energy micro-focus ray source (voltage <...
