Stanford Synchrotron Radiation Lightsource

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).

BL4-2 is a small-angle scattering station dedicated to structural biology studies primarily on non-crystalline systems. The 20-pole wiggler in combination with the multilayer monochromator provides high brilliance x-ray beam for time-resolved studies down to milliseconds. This facility covers the range of characteristic length scale of a few Angstroms to a few micrometers by the combined use of a pin-hole geometry camera, which can be automatically configured to have one of 7 sample-to-detector distances, and a separate ultra small angle scattering setup.

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.
