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

  • A Penning trap for precision mass measurements
  • 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 in November 2013
  • 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.
