As part of this year’s RWTH anniversary celebration of the 1999 graduating class, it was a great pleasure for us to welcome some of the former graduates back to the research facility of the 2nd Institute of Physics. (The jubilarians from left to right: Dr. Michael Fischer, Dr. Frank Dillmann, Dr. Jochen Dreßen, Dr. Andreas Rosenberger. Hosts at the institute: Dr. Bernd Beschoten and Prof. Dr. emer. Gernot Güntherodt)."
