Aim & Scope

The realisation of coherent X-ray beams with sufficient photon flux has attracted the interest of researchers from many diverse disciplines, including physics, material-science, chemistry, biology, and engineering. Coherent x-ray diffraction imaging (CXDI) describes several techniques, from coherent diffraction imaging of isolated specimens to X-ray ptychography of extended samples, in both forward and Bragg scattering geometries. Since CXDI can provide quantitative information in terms of electron density and morphology, new routes for quantitative analysis of different materials have been opened. In addition, the exploitation of bragg peaks, the so-called Bragg-CXDI techniques, provide the lattice distortion in a crystalline sample at sub-angstrom resolution and hence access to individual defects.

During the phase I upgrade of the ESRF special attention was paid to the development of beamlines to exploit the improved coherence of the Extremely Brilliant Source (ESRF-EBS) using the aforementioned methods. Their improved resolution has paved the way for new insight in many fields, examples include cell imaging, strain imaging in functional nanomaterials, morphological and compositional studies of pollutants, deactivation of catalytic samples by coking, the hydration of eco-cement paste, defects in microelectronics chips and novel materials for the aerospace industry. With the phase II upgrade the ESRF - EBS will allow unprecedented resolution in both space and time courtesy of the improved source. This will enable the development of new coherent diffraction methods and catapult those already existing into a new domain of possibility.

The aim of this user-dedicated meeting is to present the new science being tackled with CXDI today, and take the opportunity to bring together both expert and non-expert users to drive the directions for development and application of the ESRF-EBS for tomorrow.
