Precision test of bound-state QED in three-electron systems
Calculations of fine structure splittings in two-electron atoms provide a precise test of bound-state quantum electrodynamics. The helium fine structure currently serves as one of the most precise QED tests in two-electron systems. ... >

First experiment in the Cryogenic Storage Ring (CSR) successfully conducted
In interstellar clouds particle densities are extremely low and temperatures can be as low as –263 °C (resp. 10 K). Thus, interstellar chemistry is significantly different from well-known terrestrial chemistry. ... >

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.
