The heidelberg EBIT: Present results and future perspectives

Abstract

The Heidelberg electron beam ion trap (EBIT) is one of the three high-energy EBITs worldwide presently in operation. In this contribution, selected recent experimental results on precision spectroscopy measurements of trapped ions in the visible and x-ray wavelength regimes, respectively, will reviewed. Moreover, interference between radiative and dielectronic recombination pathways is demonstrated for Hg75+...78+ions and state selected electron transfer reactions in collisions of U64+with He is reported. Future perspectives with two new EBITs coming into operation in 2005 for the investigation of radioactive ions as well as the interaction of highly charged ions with intense photon beams from the free electron laser at DESY in Hamburg will be highlighted. © 2007 IOP Publishing Ltd.
