title: X-ray imaging – towards studies of condensed matter at the mesoscale
abstract:
X-ray imaging has developed rapidly over the last decade, with technological advances that have made X-ray imaging methods applicable to virtually all branches of the natural sciences and manufacturing industries. The unique advantages of X-ray imaging reside in the combination of high resolutions both in space and time, a relatively high transmission giving access to buried-in structures, and open access to the sample, allowing for the use of complex sample environments.
The seminar will give an introduction to the basics of modern X-ray imaging, together with examples demonstrating the principles and performance limits for state-of-the-art methods. The overview also serves as a platform for introducing the Hard X-ray Transmission Microscope (HXTM), a new instrument being under development at the European Synchrotron Radiation Facility (ESRF). HXTM will be delivering several operating modes, and allow for in situ studies of buried-in structures at length- and timescales suitable to address mesoscale processes in condensed matter.
