Abstract

Synchroton facilities worldwide provide scientists with useful radiation in the ultraviolet to the x-ray regime. Third-generation synchrotron sources will deliver photon fluxes in the 10¹⁵ photons/s/0.1%BW range, with brilliance on the order of 10¹⁸ photons/s/0.1%BW/mrad²mm². Along with the increase in flux and brilliance is an increase in the power and power densities of the x-ray beam. Depending on the particular insertion device, the x-ray beam can have total power in excess of 10 kW and peak power density of more than 400 W/mm². Such high heat loads are a major challenge in the design and fabrication of x-ray beamline components. The superior thermal and mechanical properties of diamond make it a good candidate as material in these components. Single crystal diamonds can be used as x-ray monochromators, while polycrystalline or CVD diamonds can be used in a variety of ways on the front-end beamline components. This paper will discuss the issues regarding the feasibility of using diamond in third-generation synchrotron beamline components.
