Thermo-mechanical properties of silicon, germanium, diamond, beryllium and silicon carbide for high heat load x-ray optics applications

摘要

Increased thermal power of the x-ray beams produced at synchrotron radiation facilities such as the Advanced PhotonSource at Argonne National Laboratory requires improvements in the thermal management of the components withwhich the beams interact. Crystals of silicon, germanium, diamond, beryllium, and silicon carbide are importantsubstrate materials in this regard. Accurate physical, thermal, and mechanical properties of these materials, especially atcryogenic temperatures, are needed in the analysis and design of high heat load x-ray components. In this paper, wepresent a collection of the relevant data, and include curve fits, when possible, for ease of use in the analysis.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
