Embodiment Construction

[0047] A preferred embodiment will be given below, and the present invention will be described more clearly and completely in conjunction with the accompanying drawings.

[0048] Such as figure 1 As shown, the base body used in the X-ray conversion target of the present invention includes a base plate 1 and a frame 2 . The frame 2 is formed with an accommodating groove. The base plate 1 is disposed in the accommodating groove and is integrally formed with the frame 2 . The substrate 1 and the frame 2 are integrated to ensure the sealing of the high-pressure coolant between the substrate 1 and the target layer, the heat dissipation performance during use and not easy to cause large thermal deformation, and the mechanical strength of the substrate is improved. , making the substrate easy to process.

[0049] Among them, such as image 3 As shown, the upper surface of the substrate 1 is provided with at least one first guide plate 3 . One end of each of the first guide plate...

Abstract

The invention discloses a base body used for an X-ray conversion target and a machining method thereof. The base body comprises a substrate and a frame, wherein an accommodating groove is formed in the frame, and the substrate is arranged in the accommodating groove and integrated with the frame. The machining method comprises the step of S1 carving a blank flat entirely into the base body. The base body used for the X-ray conversion target is easy to machine, good in sealing performance and high in mechanical strength, dimensional accuracy of machining and heat dissipating capacity in use are guaranteed, and severe thermal deformation does not occur easily.

Description

technical field [0001] The invention relates to an X-ray conversion target, in particular to a substrate for the X-ray conversion target and a processing method thereof. Background technique [0002] Electron beam conversion into X-rays usually bombards a target material with a high-energy electron beam, releasing X-rays through the bremsstrahlung process between the electrons and the material. Since the energy of X-rays used in industry is usually lower than 10MeV, more than 80% of the energy will be released as heat during the interaction between electrons and materials in this energy range. Therefore, a conversion target with higher power has higher requirements on the overall heat dissipation capability. [0003] Generally, the conversion target requires a coolant to cool the target material layer of the conversion target. The coolant flows between the target material layer and another sealing layer at high pressure and high speed, which exerts great pressure on the tu...
