Safety Stand-Down
SLAC has initiated a safety stand-down due to an electrical accident on site. This affects restarting the SSRL accelerator. In addition, a transformer failure has impacted SSRL operations, and its repair is delayed due to the stand-down. All SSRL user experiments through the third week of April have therefore been canceled at this point. SSRL will restart operations as soon as possible after receiving work authorization, and in compliance with new safety protocols under development at SLAC. Additional information will be provided as it becomes available, and SSRL will make every effort to minimize user impact due to this unscheduled downtime.
Macromolecular Crystallography
The SMB macromolecular crystallography (MC) program is a major experimental driver for structural biology research, serving the needs of a large number of academic and biotech groups working in this area, particularly in the Western U.S, developing, providing and supporting cutting-edge technologies for a wide-range of user applications.
Small Angle X-ray Scattering
X-ray scattering from partially ordered arrays of biomolecules typically provides low-resolution (≥ 7-10 Å) structural information under biologically relevant conditions. Studies are relatively fast, require small quantities of material and are well-suited for time resolved measurements. Applications range from conformational change to folding intermediate studies.
X-ray Spectroscopy & Imaging
Metal ions have key roles in biological structure and function - from being active sites of many enzymes to having roles in signaling pathways and being key elements of cancer chemotherapies and disease-related biological malfunctions. Synchrotron x-ray spectroscopies are a key tool in determining the geometric and electronic structure of metal centers.
