BL10-1 is primarily used for x-ray absorption and photoemission spectroscopies. The optics and control software can be run in continuous scanning mode. A few facility chambers, including cryogenic sample handling and detectors are available upon request.
BL8-1 is equipped with a post-monochromator beam-splitting mirror to allow for two sample chamber locations. BL8-1a accommodates roll-on user chambers. BL8-1b is under modification to provide energy range from 2eV to 10eV. The mirror cooling system was upgraded in FY04 and the BL8-1 stations are SPEAR3 500 mA compatible. Stations 8-1a and 8-1b cannot be used simultaneously.
BL7-2 is dedicated to x-ray scattering and diffraction experiments in materials and environmental science. Because of high demand, research is confined to problems that can only be addressed with this unique facility. Typical programs involve intrinsically weak scattering systems, such as two-dimensional arrays and high-resolution 3-D problems.
BL6-2 has an in-vacuum LN2-cooled monochromator and is windowless up to a 127μm Be window in the hutch. For high-energy applications, a toroidal Si M1 mirror is used as post-monochromator focusing element. For soft-energy applications, the M2 mirror is used for harmonic rejection.
The BL5-4 station is a normal incidence monochromator beam line optimized for high-resolution angle-resolved photoemission spectroscopy (ARPES) in the photon energy range of 10-40 eV. The dedicated experimental end station is equipped with a SCIENTA R4000 electron spectrometer operating in the parallel multi-angle recording mode. In conjunction with the normal incidence monochromator, this system is capable of performing ARPES experiments with a total energy resolution of a few meV and an angular resolution of 0.3°.
BL4-3 is dedicated to x-ray absorption spectroscopy measurements with special capabilities for soft-energy (2.4-6 keV) studies in addition to hard x-rays. Equipment includes multi-array Ge detectors, LHe cryostat and soft x-ray instrumentation. Applicationas include mainly MEIS, biology and materials science, with some use in chemistry andphysics. This station enables soft x-ray measurement (from S K-edge and up).
BL4-1 is an unfocused beam line dedicated to x-ray absorption spectroscopy measurements in the hard x-ray energy range (~5.5-38 keV). Equipment includes a 13-element detector, Lytle detector, and available LHe or LN cryostats. Applications include mainly MEIS, chemistry, catalysis and materials science.
The hard x-ray imaging station at BL 2-3 is a dedicated imaging facility which has the ability to perform a wide series of experiments, including x-ray fluorescence imaging, micro-spectroscopy (i.e. micro-XANES and micro-EXAFS), spectroscopic imaging (mapping an elemental distribution at several energies within the absorption edge of an element), micro-diffraction, and micro-tomography.
BL2-1 is a dedicated powder and thin film diffraction station. It is equipped with Huber 2-circle goniometer, a high-resolution crystal-anlyzer detector, and several different types of sample stages, including a motorized xyz state, a "wet" liquid sample stage and a cryostat (temperature range 4 K - 350 K). Analysis software provided include Origin (from Microcal), GSAS (Rietveld analysis), and a searchable powder diffraction database. The main user communities are materials science, environmental science and archaeometry.
