Dedicated High-Resolution Powder Diffraction Beamline at the Advanced Photon Source

A high-resolution x-ray powder diffraction beamline that exploits the high flux, high energy resolution, and precise energy tuning of the third-generation synchrotron source will be built at the Advanced Photon Source (APS). The goal is to establish a high-resolution high-throughput dedicated powder instrument at the APS to serve the powder community. We describe design of the instrument that is able to measure a complete high-resolution powder pattern in one hour or less, uses automation to optimize throughput, has the ability to readily tune over a wide range of x-ray energies quickly and easily covering important absorption edges for resonant data measurements, and has the ability to accommodate various environmental devices for high-temperature, low-temperature or time-resolved data collection.
