The Tenth United States National Conference on Synchrotron Radiation Instrumentation was held June 17-20, 1997 at Cornell University in Ithaca, NY. The SRI National meeting is held every two years, and this year was hosted by CHESS, the Cornell High Energy Synchrotron Source. As a national meeting, it serves as a venue for all light sources in the United States to discuss the latest, most advanced capabilities in the fields of X-ray and VUV synchrotron radiation. Topics for this year's meeting included: Facilities: history, status, and upgrades Sources: insertion devices, laser, excited and other High-tech: beam stabilization, beamline hardware, and control Optics: novel design, fabrication, testing and use Small stuff: making and imaging micro structures Real-time: in-situ measurements and materials characterization Detectors: large, small, fast, and energy-resolving

These proceedings collect the papers presented at the Eighth International Conference on Synchrotron Radiation Instrumentation, held in San Francisco, August 25th to 29th 2003. This conference takes place every three years, hosted by synchrotron research centers around the world. It is the principal meeting for developers of synchrotron radiation techniques. This particular meeting hosted 650 delegates and there are about 350 published papers in the proceedings. This proceedings series is an essential reference work for practitioners of the field. It documents the evolution and development of techniques. Many of the ideas that become standard practice in synchrotron radiation research appear first in these volumes, often with the definitive explanation and rationale for the technique in question.

The SRI2006 Proceedings features the most recent developments in present synchrotron radiation sources. It also features up-to-date free electron lasers atphoton energies from the infrared to hard X-rays, beamline instrumentation to transport the radiation to the experiments, as well as experimental techniques to utilize it. Further included are recent experimental results in synchrotron radiation sciences.
