Topic : Development of X-ray lenses for nano-beam

  

 Scope  

                        For a few decades, most of the advancements in materials science have relied a lot on material characterizations in nanoscale. Among the engineering developments which aim to improve the spatial resolution of scientific tools to nanometer-scale, those at synchrotron facilities have succeeded in producing X-ray beam with the size down to less than 10 nanometers, allowing several modern synchrotron techniques to investigate inhomogeneity of materials leading to novel information that benefit research from many different fields. Fresnel’s zone plates, which is the diffractive X-ray focusing elements, are probably the most common choice in focusing soft X-ray and medium-energy X-ray. Compared to the others, zone plate setups are compact and can thus be integrated to most end-stations at existing beamlines and also for the future beamlines operating at the new 3 GeV SPS-II Synchrotron which is planned to be built in the near future.
                        This project is of interest for Ph.D. students/candidates who would like to work on the micro and nanofabrication techniques. We are looking for a motivated student, with clean room basic knowledge; the student will be involved in the design and fabrication of Fresnel’s zone plates on a silicon wafer, as well as choice of materials to be patterned, collaborating with SLRI beamline scientist and the experts from other modern synchrotron facilities. Based on the results, the students will be able to participate in the optimization of the Fresnel’s zone plates to be applied in the new 3 GeV SPS-II Synchrotron beamlines.
