(Photo by Brad Plummer.) A new spectroscopy instrument has been installed on Beamline 6-2 at the Stanford Synchrotron Radiation Lightsource, where staff scientists are now working to test its various components before offering beam time to users this spring. Differences in synchrotron radiation beamline shielding design between the facilities of 3GeV class and 8GeV class are discussed with regard to SLAC SSRL and SPring-8 beamlines. Summary: SSRL will be implementing a dedicated quick scanning monochromator for X-ray absorption spectroscopy (QEXAS) on BL10-2 in the fall of 2021, making it the first such monochromator on an wiggler beamline. Exciting news! For the first time since shelter-in-place in early March we are now back at the beamline conducting in-situ/operando XAS experiments. On Oct 14th, we began experiments at beamline 9-3 under the strict COVID-19 protocols that are in place at SSRL/SLAC. Instead of users being physically present at the beamline, the Co-ACCESS staff are conducting the experiments with the This article describes a high-resolution three-dimensional CT system which has been tested on the new wiggler beamline X-2 at the Stanford Synchrotron Radiation Laboratory.

Beam line 4-1 is optimized for XAS measurements between ~5.5 and 30 keV, whereas BL 4-3 is optimized for experiments at 2.4 to 7 keV. X-ray Scattering at SSRL
edge X-ray absorption spectra were collected on beamline 4−3 at the SSRL operating at 3.0 GeV and 100−200 mA. Methods are described in the SI. Spectral analysis was performed with the program SIXPAK.31 Background before the edge was subtracted using a linear ﬁt to the pre-edge region and spectra were normalized to the postedge step height.

Carmen at beamline Published January 3, 2020 at × in Carmen at beamline Carmen in preparation at SSRL beamline 4-2 before blasting some poor macromolecules with hard X-rays. Ptychography is an emerging high resolution coherent imaging technique which can improve the resolution of current scanning transmission X-ray microscopy systems by over ten-fold. Development of this capability is underway at Stanford Synchrotron Radiation Lightsource, SLAC National Accelerator Laboratory, to establish sub-5 nm resolution ptychographic imaging with spatially resolved near-edge

The 20-pole wiggler of Beam Line 4-3 produces high-resolution x-ray spectra in the 2.4-14 keV energy range that makes Beam Line 4-3 especially useful to study the elements sulfur, chlorine, and calcium, which are important to biology, geology and archaeology. Science is the search for the unexpected, and Beam Line 4-3 is a great facilitator. SSRL offers more than 30 experimental stations, supporting a variety of techniques including: macromolecular crystallography, soft and hard x-ray microscopy, microXAS imaging, x-ray scattering and diffraction, photoemission spectroscopy and x-ray absorption and emission spectroscopies.

Using SSRL Beam Line 4-3, a team of SSRL and University of Palermo researchers measured
Beamline 4-3 is a wiggler side-station beamline dedicated for X-ray absorption spectroscopy and EXAFS measurements on biological and environmental systems. This station enables tender X-ray measurement (S K-edge and up) and is setup with a He flight path from the beamline optics to the sample.

SSRL offers more than 30 experimental stations, supporting a variety of techniques including: macromolecular crystallography, soft and hard x-ray microscopy, microXAS imaging, x-ray scattering and diffraction, photoemission spectroscopy and x-ray absorption and emission spectroscopies. Beamline 4-3 was newly reopened as of 4/6/2009 bringing special capabilities for soft-energy (2.4-6 keV) studies in addition to hard x-rays. Beamline 4-3 now replaces 6-2 as the preferred location for Sulfur K-edge experiments at SSRL. 2018-02-20 · Beam line 7-3 is a wiggler side-station dedicated for x-ray absorption spectroscopy and EXAFS measurements on dilute biological systems.
For SSRL operations, 1988 was a year of stark contrasts. Laboratory/SSRL ( Beam Line 6), University of Branch Line 4-3 Improvement Program - A new. 1 Jan 1997 XAFS data for the glasses and melts were collected on beam line 4-3 at SSRL ( Stanford) with a Si-(220) two-crystal monochromator, the Sulfur XAFS was measured at room temperature at beamline 4-3 of SSRL configured in low energy mode using a 4-element Ge detector.
SSRL has recently returned to extended running following the successful commissioning of a dedicated injector, and operation of the SPEAR storage ring exclusively for synchrotron radiation research.
