Hands-on: Tomography

On-site | 3 Dec 2021 | Grenoble, France

This hands on training is one day practical session using either Lab X-ray tomography, X -ray tomography at ESRF. This session aims at using tomography on your own problem. During this session you will prepare the best conditions of your experiment on your own material problem with help of experts and simulation tools and realize data acquisition, reconstruction and data analysis. This is an on site course and you will be in contact with the professor before the session to define the best type of source (Laboratory or synchrotron) for your case.
