SSRL Beamline 5-4 UV or x-ray photons are directed onto a sample where they interact with the electrons within the sample, ejecting them into the vacuum. By analyzing these emitted electrons, we can learn about the properties of electrons within the sample.

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). 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.

Our group helps the maintenance of three beamlines, SSRL beamline 5-4, SSRL beamline 5-2 and ALS beamline 10.0.1, respectively. Following are some of their descriptions.

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.

Last week, X-ray light for the first time streamed into the new Beamline 14-1 hutch at the Stanford Synchrotron Radiation Lightsource.

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.

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.
