The experimental working group of the division is concerned with precision experiments on stored and cooled ions as well as with the investigation of fundamental processes of molecular ions. For this purpose short-lived radionuclides, highly-charged ions or simple molecular ions are trapped in Penning ion traps and storage rings under conditions as they also occur in space. Another main research field of the division is the development of novel storage, cooling and detection techniques for future experiments.
