Techniques
Available techniques and variants
The available equipment and instruments on D2AM offer the possibility of conducting a wide variety of scattering and diffraction techniques. These techniques grant access to reciprocal space near its origin or close to a given Bragg reflexion. It is therefore possible to perform small-angle X-ray scattering (SAXS), wide-angle X-ray scattering (WAXS) or 3D reciprocal space mapping. Thanks to additional and optional sample motorization (cradles), grazing incidence configurations are also possible.
In addition, the design of the beamline optics allows performing energy scans over several hundreds of eV without changing the beam position on the sample. This fixed point exit feature offers to the beamline the capability of performing anomalous scattering.
Moreover, measurements under continuous scan modes are now possible. Any configuration and combination between these features are possible. Measurements such as AGISAXS (anomalous grazing-incidence small-angle X-ray scattering), GIXRD, ASAXS, RXRD (resonant X-ray diffraction) are frequently conducted at the beamline.
The combination of all these features made the beamline a highly efficient tool for advanced temporally, spatially and energetically resolved in situ characterization in materials science.
In this section, we will describe the basic and principle experimental configuration for the main techniques: Diffraction, SAXS, and WAXS
