A unique polarized x-ray facility at the Advanced Photon Source

To use the unique element-specific nature of polarized x-ray techniques to study a wide variety of problems related to magnetic materials, we have developed a dual-branch sector that simultaneously provides both hard and soft x-ray capabilities. This facility, which is located in sector 4, is equipped with two different insertion devices providing photons in both the intermediate (0.5-3 keV) and hard x-ray regions (3-100 keV). This facility is designed to allow the simultaneous branching of two undulator beams generated in the same straight section of the ring. (C) 2002 American Institute of Physics.
