Review article on the cryogenic storage ring CSR
Ion storage rings are unique tools for investigating properties and interactions of atomic and molecular ions. The astrophysically relevant dissociative recombination of molecular ions with electrons can be investigated as well as the de-excitation of internal states in atomic ions and in small to very large molecular systems. ... >

  • A Penning trap for precision mass measurements
  • Electrodes of a Penning trap
  • An ion with only one electron stored in a cylindrical Penning trap
  • 7 T superconducting magnet for PENTATRAP
  • A liquid-nitrogen-cooled GaAs photocathode producing electron beams with internal temperatures down to 10 K
  • View onto the CSR just before its commissioning at cryogenic temperatures in April 2015
  • Copper strips distribute the cold to the experimental vacuum chambers of the CSR
  • CAD drawing of the laser photodetachment line for injection of neutral atomic or molecular beams into the CSR
  • Artist's view of the reaction between protonated water and electrons in the CSR
  • Profile of the first beam of argon ions in the not yet cooled CSR on March 17, 2014
  • The cryogenic ion trap used as a prototype for the CSR

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 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.
