Abstract

The composite photovoltaic anode, leveraging the unique characteristics of a composite structure and high thermal conductivity materials, is progressively replacing traditional sample anodes in X-ray sources. This paper elucidates the structure of the diamond-based X-ray source anode (referred to as the “composite anode”). By incorporating a diamond layer, the composite anode aims to achieve rapid heat conduction and high-temperature durability. The characteristics and thermal conductivity weight of the diamond layer are explored. Furthermore, finite element analysis (FEA) methodology is employed to simulate and compare different thicknesses of the diamond layer. The findings illustrate that the diamond layer in the composite anode structure exhibits a high thermal conductivity rate and high melting point characteristics. Additionally, the thickness variation of the diamond layer directly impacts the overall heat conduction capacity of the composite anode. Consequently, the relationship between the thermal conductivity coefficient of the composite anode and the thickness of the diamond layer is ascertained, provided that the experimental conditions allow for reproducibility.
