Transform target device and target material layer structure

Abstract

The invention provides a transform target device which comprises an upper frame, a target material layer, a cooling cavity frame and a sealing layer, wherein the target material layer is fixed on thecooling cavity frame by the upper frame; the sealing layer is fixedly connected with the cooling cavity frame, and the target material layer, the cooling cavity frame and the sealing layer form a cooling cavity; the cooling cavity comprises a cooling liquid inlet and a cooling liquid outlet; the target point of the target material layer is arranged to be conical. The invention further provides a target material layer structure which comprises a target point position. X-rays are generated when the electron beam interacts with the target point position of the target material layer structure; andthe target material layer at the target point position is conical. By optimizing the structure of the planar target, the transformation efficiency of the target is improved, and the irradiation dosedistribution and the heat dissipation effect of the target are improved.

Description

technical field [0001] Embodiments of the present invention relate to a conversion target device and a target material layer structure. Background technique [0002] In the field of radiation processing, X-rays, γ-rays and electron beams are usually used as radiation sources for processing and production. Compared with the three ray sources, the X-ray source has the advantages of strong penetrating power of the γ-ray source and good orientation of the accelerator electron source, high radiation intensity, high efficiency and good safety, and has a large thickness and density. The advantages of X-ray sources are even more obvious when irradiating objects. The X-ray generation devices used for irradiation processing can be mainly divided into two categories, namely radionuclide decay and the use of high-energy electron beams to target X-rays; for example, the common electron linear accelerator is generated by the electron beam output from the accelerator The emission rate of...

[0006] (3) When the high-energy electron beam is vertically bombarding the heavy metal conversion target, when the conversion target is a planar design, it is easy to cause the target points to be concentrated within a radius of several millimeters, resulting in a small heat dissipation area and concentrated heat generation, so the heat dissipation effect is poor and easy Causes damage to conversion targets and reduced service life
