Research of Anode Structure of High Emission Flux X-ray Source Based on Composite Structure

Abstract

This study presents the design of an X-ray source anode structure that can boost X-ray emission flux. The construction makes use of the properties of the composite structure to increase thermal conductivity of the anode. To indirectly enhance the X-ray output flux, the number of electron beams at the source is increased. In addition to explaining the composite anode’s design and manufacturing process, this paper concentrates on a study of the material’s thermal conductivity. X-ray flux of several anode are simulated and compared using finite element analysis (FEA) techniques. It was found that the substrate material for the composite anode construction needed to have a high melting point and thermal conductivity. The characteristic enables rapid conduction of the heat produced in focal region of the anode. In addition, the anode’s thermal stability is assured while the high temperature phenomena brought on by energy buildup is prevented. It establishes the framework for making subsequent anodes.
