Data Source - Instrument Synchrotron Radiation Lightsource 14-3

Stanford Synchrotron Radiation Lightsource Experimental Station 14-3b is a bending magnet side station dedicated to X-Ray Imaging and Micro X-Ray Absorption Spectroscopy of biological, biomedical, materials, and geological samples. Station 14-3b is equipped with specialized instrumentation for XRF imaging data collection in the Tender X-Ray Absorption Spectroscopy regime of 2-5 KeV. Capabilities for XRF Imaging and XANES Spectroscopy is captured between 2100 and 5000 eV. Sigray achromatic paraboidal lenses are used to achieve microfocus with a beam size of either 1 or 5 microns. BL14-3b is ideal for obtaining elemental maps or small samples (~ 20 µm to 25 mm) as well as performing XANES on selected points in the sample (~5 µm2). Sample positions are controlled using submicron accuracy by a Newport sample stage and an inside He purged sample chamber. Synchrotron data source acquisition for XRF Imaging, micro-XAS, and XANES Imaging  and processing software SAMware can be found at the BL14-3 Wiki page. For more information, including beam line specifications, visit the SSRL Experimental Station 14-3b homepage.
