Success for cryogenic ion catcher

07 November 2011

After successful commissioning with a radioactive source at KVI in early 2011, the cryogenic ion catcher was tested for the first time in realistic experimental conditions in October 2011 at GSI. The results show that the system works as intended. During this first test ever of a cryogenic ion catcher, a helium gas density several times larger than ever achieved with comparable, but 'warm', ion catchers was used. This is very important given the large energy of the ions to be captured. Further tests with the system are planned for Spring 2012.

Many scientific disciplines make use of radioactive isotopes in the form of a low-energy ion beam or an ion/atom cloud in a trap. New and planned in-flight facilities optimally produce and select radioactive isotopes at very high energies. Techniques to efficiently and quickly transform high-energy ions to low-energy ones are thus essential.

Within the agreement between the University of Groningen and the GSI Helmholtzzentrum für Schwerionenforschung ( Darmstadt , Germany ), and in collaboration with partners from the Justus-Liebig Universität in Giessen and GSI, KVI has developed a so-called cryogenic ion catcher. It stops high-energy ions in cold helium gas (temperature about -200 Celsius) and uses electric fields to guide the stopped ions to a small exit hole from which they appear as a low-energy ion beam.
