摘要：

In the past decade, several third-generation synchrotron x-ray sources have been constructed and commissioned around the world. Many of the major problems in the development and design of the optical components capable of handling the extremely high heat loads of the generated x-ray beams have been resolved. It is expected, however, that in the next few years even more powerful x-ray beams will be produced at these facilities, for example, by increasing the particle beam current. In this paper, the design of a next generation of synchrotron x-ray mirrors is discussed. It is shown that contact-cooled mirrors capable of handing x-ray beam heat fluxes in excess of 500 W/mm(2) (more than three times the present level) can be designed. The limiting factor in these mirrors is thermal stress rather than thermally induced slope error.
