Finally! After a forced break due to Corona, we started again. The Blum WG went to Boiensdorf-Werder on the Baltic Sea from 08.05.-12.05.2023 for a joint working retreat and spent a week full of intensive work on research topics and group activities. A special highlight was an excursion to Greifswald to the Max Planck Institute for Plasma Physics with a visit to the Wendelstein 7-X nuclear fusion experimental facility followed by a visit to the Melzer WG at the University of Greifswald, where an insight into the world of dusty plasmas was provided.
