Welcome to the homepage of the Stored and Cooled Ions Division
Director: Prof. Dr. Klaus Blaum

  • PENTATRAP trap tower
  • PENTATRAP Penning trap mass spectrometer
  • ALPHATRAP trap tower
  • ALPHATRAP Penning trap precision lab
  • A liquid-nitrogen-cooled GaAs photocathode producing electron beams with internal temperatures down to 10 K
  • 3D drawing of the CSR (August 2019)
  • 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
  • Gold-plated mirror for a novel detector module in mid-infrared at the Cryogenic Trap for Fast ion beams (CTF)
  • 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 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.
