Beam line 7-3 is a wiggler side-station dedicated for x-ray absorption spectroscopy and EXAFS measurements on dilute biological systems. BL7-3 is equipped with a 30-element Ge solid-state detector in addition to ionization chambers and Lytle/PIPS detectors. A dedicated LHe cryostat allows for routine low temperature measurements. The unfocused beam on BL7-3 is ideal for samples especially susceptible to radiation damage, such as high-valent intermediates and other oxidized species.
Beam line 7-1 is a 8-pole, 2.0-Tesla wiggler side-station beam line optimized for monochromatic, high-throughput, high-resolution macromolecular crystallography. It is SAD and MAD capable and can be run in a full remote access mode. It is equipped with an ADSC Q315R CCD detector. Currenlty 7-1 is dedicated to staff development and user training.
See the Macromolecular Crystallography website for details.
Beam line 6-2b is a wiggler end-station dedicated to High Resolution Hard X-ray Spectroscopy. The end station combines three multicrystal Johann spectrometers that enable X-ray Emission Spectroscopy (XES), Resonant Inelastic X-ray Scattering (RIXS), High-Energy Resolution Fluorescence Detected X-ray Absorption Spectroscopy (HERFD-XAS) and X-ray Raman Spectroscopy (XRS) techniques.
Beam line 6-2a is a wiggler end-station that can be configured for tender x-ray x-ray emission spectroscopy (instrumentation in commissioning use).
Beam line 2-3 is a bending magnet side station dedicated to x-ray imaging and micro x-ray absorption spectroscopy (edge, EXAFS) as well as micro diffraction of biological, material, and geological samples. A set of SIGRAY axially symmetric mirror systems are used to achieve a microfocus with an option of a beam size of ~ 3 x 3 microns, or sub-micron spots. The energy range of the beam line optics covers 4.9-23 keV, with detection of fluorescent x-rays as low as Si. BL2-3 is equipped with a Vortex silicon drift detector and ionization chambers.
Beam line 2-2 is currently closed.
Beam line 4-1 is a high-flux station optimized for x-ray absorption spectroscopy and EXAFS experiments requiring x-rays with energies between ~ 6 and 38 keV. This energy range includes most of the transition metals (all rows), lanthanides and actinides, P-block elements, alkaline and alkaline earths. While it is possible to access x-rays as low as 5 keV, these experiments are challenging because of air absorption and are better performed at BL4-3.
Beam Line 4-2 is a permanent experimental station for small-angle X-ray scattering and diffraction (SAXS) techniques dedicated to research in structural biology and biophysics. The station provides state-of-the-art experimental facilities for structural studies on biological material such as nucleic acids, proteins, protein assemblies, virus particles, biological fibers as well as lipid membranes and membrane-protein/DNA complexes.
Beam line 4-3 is a wiggler side-station dedicated for x-ray absorption spectroscopy and EXAFS measurements on biological, environmental, catalysis, and materials systems. This station enables tender x-ray measurement (S K-edge and up, i.e. 2.4-5 keV) in addition to hard x-rays ( up to 11 keV). It is setup with a He flight path from the beam line optics to the sample. The beam is collimated and unfocused to allow for high energy-resolution measurements on homogenous samples.
