The scientific module on x-ray tomography aims to provide a general overview of existing hard and soft x-ray microscopy methods for macro and nano imaging. Apart of theoretical background it will include hands-on practical work on how to prepare soft materials to improve x-ray absorption, mounting strategies for specimens, optimal imaging parameters, reconstructions and 3D volume analysis. By the end of this course, participants should be able to choose method and protocol of interest depending on the question within their own scientific field. Participants are welcome to suggest/bring their own specimens. The course will be held in English.
