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 14-3b, located on the downstream table in the BL14-3 hutch, is a bending magnet side station dedicated to x-ray imaging and micro x-ray absorption spectroscopy of biological, biomedical, materials, and geological samples. Most often used for data collection at the S K edge, BL14-3 is the only SSRL beam line capable of XAS at the P K edge. During imaging mode, a SIGRAY axially symmetric mirror system is used to achieve the microfocus with a beam size of ~ 5 x 5 microns, or sub-micron sizes.
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 14-1 is a bending magnet side station. It is dedicated for monochromatic, high-throughput macromolecular crystallography and optimized for SAD and MAD experiments. It can be run in a full remote access mode. It is equipped with a Rayonix MX325 CCD detector.
See the Macromolecular Crystallography website for technical details.
Beam line 12-2 is a PRT station, realized through third party funding from the Gordon and Betty Moore Foundation via the California Institute of Technology and available to general users 70%; it is a 134-pole, 1.0-Tesla in-vacuum undulator beam line with fully adjustable focus from 100 to 15 microns. smaller beams can be achieved by the use of microcollimators. It is optimized for microdiffraction, monochromatic, high-throughput and high-resolution macromolecular crystallography. It is SAD and MAD capable and can be run in a full remote access mode.
Beam line 12-1 employs a 154-pole, 1-Tesla in-vacuum undulator, a flat side-deflecting Rh-coated Si mirror, and a liquid nitrogen-cooled double-crystal Si(111) monochromator with a 0.01% energy bandpass. The beamline is also fitted with a multilayer with a ~1% energy bandpass that boosts the x-ray flux by a factor by about two orders of magnitude.. Kirkpatrick-Baez (KB) optical mirrors are used for 18:1 horizontal and 12:1 vertical beam focusing. The vertical mirror polish is ~100 nrad RMS and a vertical beam focus of ~5 µm FWHM.

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 9-2 is a wiggler end station dedicated for monochromatic, high-throughput and high-resolution macromolecular crystallography and optimized for SAD and MAD experiments. It can be run in a full remote access mode. It is equipped with a Dectris Pilatus 6M PAD detector and a remote access controlled UV-Vis microspectrophotometer.

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.
