Small Angle X-ray Scattering
Small Angle X-ray Scattering has become a well known standard method to study the structure of various objects in the spatial range from 1 to 1000 nm, and therefore instruments capable to perform such experiments are installed at most of the synchrotron research centers. The high-flux SAXS beamline at ELETTRA is mainly intended for time-resolved studies on fast structural transitions in the sub-millisecond time region in solutions and partly ordered systems with a SAXS-resolution of 1 to 140 nm in real-space.
The photon source is the 57-pole wiggler whose beam is shared and used simultaneously with a Macromolecular Crystallography beamline. From the very intense wiggler radiation, the SAXS-Beamline accepts 3 discrete energies, namely 5.4, 8 and 16 keV (0.077, 0.154, 0.23 nm). The beamline optics consists of a flat, asymmetric-cut double crystal monochromator and a double focusing toroidal mirror.
Areas of research
On-line data analysis
The SAXS beamline represents a complex data collection process, with specific processing, storage, anaysis and sharing and visualisation requirements. This kind of application requires both the support of a standard Grid computing environment, that is a virtual organisation, a set of distributed storage and computing resources and some resource brokering mechanism, a workflow definition and execution environment and the capability to integrate instruments (the detectors) and interactively collaborate in the data analysis process.Back to top
