15 students participated in the block course "Ion beam analysis 2014", which took place at the Accelerator and Isotopes Laboratory of the RUBION of the Ruhr university Bochum for 1 week. The participants learned how to modify and analyse materials. Here are some impressions. Among others, optical materials were investigated and a PhD student's tooth analysed in terms of Fluor traces originating from toothpaste. The final colloquium will be held on 15th April in Paderborn.
