Research at XRD1

XRD1 and its Users

The XRD1 beamline was among the first to become operational at Elettra and has been recently upgraded after more than ten years of function. Proposals requesting beamtime at XRD1 are submitted to the Elettra Proposal Review Panel for evaluation from heterogeneous group of researchers affiliated with national and international research centers and universities. The beamline is also actively involved in collaborations with industrial partners.
Users submitting a proposal for the first time are warmly invited to browse our publications, in order develop a clear view on the typical applications of our setup and its capabilities.

Research Fields

The XRD1 beamline has been designed primarily for macromolecular crystallography, but the characteristics of the beamline permit to perform a wide variety of experiments: the beamline hosts small molecules, protein crystallography, powder diffraction, high pressure physics and solid-state experiments. Research takes place in fields related to biology, pharmaceutics, chemistry, materials science, archeometry, food science, geophysics, solid state and superconductors physics.
The light source with a useful energy range from 4 to 21 keV and the availability of a kappa goniometer make XRD1 a powerful tool: selected examples of XRD1 applications can be found in our Highlights section.

Protein Crystallography

Small Molecules


Protein crystallography is one of the most powerful techniques for the determination of 3D structure at atomic level of proteins and large cell macromolecules. The Si 111 monochromator allows to select the energy in the range 4 to 21 keV, in MAD experiments it is necessary to perform fine scans in wavelength to determine the absorption edge of a specific element

The small molecules studies take advantage from the high intensity of the x-ray beam and from its natural collimation.



Powder Diffraction

Holography

Powder diffraction is an analytical tool for both qualitative and quantitative analysis of crystalline materials. It is widely used for polycrystalline compound. Synchrotron sources provide powerful tools to this technique that take advantage by intense and high collimated x-ray beams.

In the internal source holography, fluorescence from the atoms inside the sample is excited, and the emitted spherical wave, approaching the far-field detector directly, forms the holographic reference wave. In other direction it is scattered by neighbouring atoms, thus giving the holographic object wave.
