Third-generation synchrotron radiation sources are capable of producing extremely intense beams of high energy x-rays with energies above 35 keV. This has provided a wide variety of important opportunities in diverse fields. Specialized undulators and optics can achieve unprecedented bri lliance and photon flux in this energy range. The use of high x-ray energies for powder diffraction largely eliminates absorption and extinction effects, and opens the possibility of obtaining very high-quality data for materials containing high-Z elements. The ability to penetrate bulk samples or environmental cells enables dynamic studies under extreme and carefully controlled conditions. The short wavelength also allows the measurement of very high Q data, providing more structural detail. High energy x-rays from third-generation sources display many of the advantages of neutrons from pulsed sources, but with much higher brightness and better resolution. We will present the optics and instruments that have been developed for high-energy x-ray diffraction at sector 1 of the SRI-CAT and for future use at the High Energy X-ray Scattering Collaborative Access Team (HEX-CAT) beamlines. Our studies of disorder in clathrate thermoelectric employing high-energy powder diffraction will be used to illustrate both the potential of high energy x-rays and the challenges associated with their use for powder diffraction. Work at the advanced photon source was supported by the u.s. Department of energy, office of sciences, office of basic energy sciences, under contract no. W-31-109-eng-38.
