Elliptical multipole wiggler beamlines at the Advanced Photon Source

摘要

The Basic Energy Sciences Synchrotrons Radiation Center Collaborative Access Teamhas built three independent beamlines, which simultaneously utilize the x-ray radiation 120m an elliptical multipole wiggler, located at Sector 11 of the Advanced Photon Source. This insertion device produces circularly polarized x-rays on-axis and linearly polarized x-rays above and below the ring plane. The lower linearly polarized radiation is used in the monochromatic 11ID-D station for scattering and spectroscopy experiments in the 5 to 40 keV range. The on-axis circularly polarized photons are used for magnetic Compton scattering experiments in the 11ID-B station. The upper linearly polarized radiation is utilized by the high-energy diffraction station, 11ID-C. We report hereon the beamline optics and experimental station equipment.
