Description
X-ray optics are used at synchrotron radiation (SR) sources to tailor the X-ray beam characteristics to the needs of the experiment. Such optics can modify the transmitted X-ray spectrum, beam size and divergence, coherence and polarisation. Due to the diversity of experimental techniques implemented in typical light sources, the optical design is usually specific to each beamline and can draw upon an extensive ‘toolbox’ of X-ray optics allowing the performance to be optimised for each application. This presentation will give an overview of the principals of operation of the most common X-ray optics used at synchrotron radiation-based light sources such as the ESRF and present their essential characteristics.
At modern SR sources, some of the more challenging aspects of the optical design are the management of the absorbed X-ray beam power on the upstream optical components and the implementation of focusing systems capable of producing X-ray beams of nanometric dimensions. Some of the technological solutions and latest developments in response to these specific challenges will be presented.
