2018-01-23 · A remote desktop application runs on the User's home computer that displays an SSRL beamline desktop; Blu-Ice and data processing programs run as if the User was at the beamline. The crystal information in the SSRL database can be loaded into Blu-Ice and crystals can be screened in an automated fashion using the 'Screening Tab'. Synchrotron radiation facilities provide a unique opportunity for low-energy x-ray dosimetry studies because of the availability of monochromatic x-ray beams. Results of such studies performed at the Stanford Synchrotron Radiation Laboratory (SSRL) are described.
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.

The list of beamline files in this directory should correspond to the list of beamline in webice.beamlines config. - Stop and restart Tomcat web server as described Dimosthenis Sokaras at SSRL Beamline 6-2. (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. 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.
By analyzing these emitted electrons, we can learn about the properties of electrons within the sample. Connecting to SSRL computers using NoMachine (NX) As most experiments are conducted remotely, the way to access the beamline control software, blu-ice, is by establishing a remote desktop session to SSRL. For this purpose, we run two servers with the NoMachine Terminal Server software. smbnxs1.slac.stanford.edu

Then, I heard through one of my mentors (a neutron scientist) that a friend of his from graduate school was looking for someone to design and commission a x-ray powder diffractometer at a beamline at SSRL. I volunteered to do so. Opportunities in Chemistry & Catalysis Research Using Quick Scanning XAS. Organizers: Simon Bare, Adam Hoffman, Oliver Mueller (SLAC/SSRL) Summary: SSRL will be implementing a dedicated quick scanning monochromator for X-ray absorption spectroscopy (QEXAFS) on BL10-2 in the fall of 2021, making it the first such monochromator on a wiggler beamline. The ability to control a synchrotron beamline remotely from the comfort of the home laboratory has set a new paradigm for the collection of high-quality X-ray diffraction data and has fostered new collaborative research, whereby a number of remote users from different institutions can be connected at the same time to the SSRL beamlines.

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. 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. Beam line 7-3 is a wiggler side-station dedicated for x-ray absorption spectroscopy and EXAFS measurements on dilute biological systems.
Brief Stacking the Deck for Custom-Built 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. The present system is a rotate-only design which uses a virtual phase CCD array camera optically coupled to a high-resolution phosphor screen. The spatial resolution of this system is presently somewhat better than 10 μm SSRL Beamline 13 Achieves First Light Light shines into Beamline 13. On February 14, the first light shone into the Stanford Synchrotron Radiation Laboratory's newest beamline. 2021-01-28 · Select the cassette type (SSRL or Puck adapter), type in the cassette number if known and click Submit. A cassette named cassette_template.xls will appear in your spreadsheet list. The spreadsheet can be assigned to a beamline and dewar position as usual.
