The experimental division "Stored and cooled Ions" deals with precision experiments to determine atomic and nuclear ground state properties of stored ions for tests of fundamental interactions and their symmetries as well as with the study of elementary processes of molecular ions. For this purpose, short-lived radionuclides, antimatter, highly charged ions or simple molecular ions are trapped in Penning traps or in the cryogenic storage ring CSR under space conditions. The development of new storage, cooling and detection techniques for future experiments is also an important research focus of the division.
