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. Mercury L 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 If beamline file can not be found, webice will use values from default.properties.

characteristics: - Elliptically bent ultrasmooth mirrors in a Kirkpatrick-Baez configuration provide micron to submicron x-ray spot size on the sample. - High x-ray flux provided by synchrotron bend magnet source. SSRL beamline BL 4-1 in transmission mode using a Si (220) double crystal monochromator. Edge calibration was performed using Zr (17988 eV) located in front of a reference ion-chamber and measured simultaneously with each spectral sample. All data processing, including normalization, was carried out using the software SIXPACK Process Variables for SSRL Beamline Users and Other SLAC Projects Some users, external to SPEAR accelerator controls, need access to a small subset of EPICS process variables (PVs) to get general SPEAR and beamline status, coordinate their activities with SPEAR injection, and move beamline inserion devices (IDs).

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. During the hiatus, the entire beamline data acquisition systems at the laboratory have been upgraded and extended to provide a more consistent, capable, and flexible interface to synchrotron users

SSRL's beamline 4- 3 using the LANL/UW tender X-ray emission spectrometer.35 Our approach. 22 Sep 2015 Mn XANES spectra were recorded at the wiggler beamline 4-3 at the Stanford Synchrotron Radiation Lightsource (SSRL) with an Si(110) ϕ = 0  current of ∼100 mA; (2) beamline 4–3 at Stanford Synchrotron. Radiation Laboratory (SSRL) using a Lytle type ionization de- tector, a Si (220) monochromator,  of niobium and tin in 29 silicate glasses was investigated by XAFS at the Nb and Sn K-edges using beamline 4-3 and 11-2 at SSRL (Stanford, USA).

Beam line 4-3 is a wiggler side-station dedicated for x-ray absorption spectroscopy and EXAFS measurements on biological, environmental, catalysis, and materials systems. This station enables tender x-ray measurement (S K-edge and up, i.e. 2.4-5 keV) in addition to hard x-rays ( up to 11 keV).

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. A beamline has been constructed at Stanford Synchrotron Radiation Laboratory (SSRL) whose radiation source is a multipole permanent magnet wiggler installed in a straight section of the SPEAR 3-3.5 GeV electron storage ring. The wiggler is a hybrid design that utilizes Nd-Fe alloy magnet material combined with Vanadium Permendur poles.
