Laser spectroscopic and theoretical investigation of the discontinuity in charge radii at shell closures
According to the shell-model picture, in atomic nuclei each shell can be filled with a certain maximal number of protons or neutrons. Completely filled shells define the so called "magic" proton and neutron numbers ... >

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

  • 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
  • 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.
