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 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 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.
