PhD Thesis Student (m/f) Subject: High Energy X-ray in-line interferometry based on refractive optics
The ESRF is a multinational research institute, situated in Grenoble, France and financed by 19 countries mostly European. It operates a powerful synchrotron X-ray source with some 30 beamlines (instruments) covering a wide range of scientific research in fields such as biology and medicine, chemistry, earth and environmental sciences, materials and surface science, and physics. The ESRF employs about 600 staff and is organized as a French société civile.
Recently a new type of hard X-ray in-line interferometer employing a bilens system consisting of two parallel arrays of planar compound refractive lenses has been proposed at the ESRF. Under coherent illumination this lens system creates an interference field with a fringe spacing ranging from tens of nanometers to tens of micrometers. This simple way to create a high energy X-ray in-line standing wave opens up the opportunity to develop new coherent imaging and diagnostics techniques, which will be applied for optics and beam characterization and for studying nanoscale materials, such as self-organized photonic and colloidal crystals.
The aim of this PhD project is to develop novel X-ray multi-lens interferometers for coherent imaging and diagnostics techniques. During your PhD thesis work, you will investigate optical properties of multilens interferometer and the influence of instrumental parameters on image quality. This work will include computer simulations of coherent image formation with an existing code in order to quantify the performance characteristics of the method in comparison to other imaging methods. In addition the student will apply multi-lens interferometry to relevant scientific problems, within the framework of existing collaborations or to new projects. This project will be carried out in close collaboration with Technical University of Dresden in Germany.
Contract of two years renewable (subject to satisfactory progress) for one year.
The working language of the ESRF is English. You should hold a degree in Physics, materials science or Chemistry allowing enrolment for a PhD, such as an MSc, Master 2 de Recherche, Laurea or equivalent.
