Beamline 15-2 is an undulator experimental station dedicated to advanced hard x-ray spectroscopy. The end station is equipped with sub-corehole lifetime resolution x-ray emission spectrometers (a 7-crystal Johann spectrometer and a 8 crystal von Hamos instrument) as well as a high-throughput and high energy resolution (0.3eV) 40-crystal low-q x-ray Raman spectrometer.
Beam line 14-3a, located on the upstream table of the hutch of the BL14-3 bending magnet side station, is dedicated to bulk x-ray absorption spectroscopy of biological, materials, and geological samples in the tender x-ray photon energy range 2.1-5.0 keV. BL14-3 is the only beam line at SSRL capable of obtaining spectroscopy data at the phosphorous K edge. In this configuration the beam is unfocused over a size of 1 mm x 6 mm to allow for high energy-resolution measurements on homogenous samples.

Beam line 11-2 is a high-flux XAS station dedicated to molecular biogeochemical and interface sciences. It is optimized for challenging XAS measurements on dilute or radioactive samples and interfaces. To support these experiments, BL11-2 is equipped with collimating and focusing optics, a "double double" Si(220) LN2-cooled monochromator, and a 100-pixel monolithic solid state Ge detector array.
Beam line currently closed for upgrade.
Beam line 10-2 is a wiggler-based source that splits time between the front hutch (BL10-2a), instrumented for wide-angle X-ray scattering, and the rear hutch (BL10-2b), instrumented for X-ray spectroscopy with a focus on in-situ, time-resolved catalyst characterization.
Beam line 9-3 is a wiggler side-station dedicated to biological x-ray absorption spectroscopy and EXAFS measurements of dilute solutions and single crystals. BL9-3 is equipped with a 100-element Ge monolithic solid-state detector in addition to ionization chambers and PIPS/Lytle detectors. A dedicated LHe cryostat allows for routine low temperature measurements on solutions. A Huber-Kappa goniometer, a LHe cryostream, a focusing polycapillary and a MAR CCD detector are available (in addition to specialized software) for single crystal measurements.
Beam line 8-2 can be used to probe a wide range of core levels using photoemission and x-ray absorption spectroscopies. At BL 8-2, currently only one end-stations is available for the general user program. The first end-station is a high throughput setup for soft x-ray spectroscopy measurement – upgrades in progress include a fixed position multipurpose chamber with a load lock system for high throughput sample loading, capable of probing a wide range of materials with absorption and photoemission techniques.
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 6-2c is a wiggler end-station dedicated to hard x-ray transmission x-ray microscopy. The BL6-2c back hutch houses a Transmission X-ray Microscope with 2D and 3D full field imaging and spectroscopic capabilities, with an instrument resolution down to 30 nm. It has specific capabilities for in-situ tomographic studies of catalytic processes including x-ray absorption spectroscopy.
Beam line 2-2 is currently closed.
