Fourier-Transform Ion-Cyclotron-Resonance Mass Spectrometry (FT-ICR MS) is a standard technique in Chemistry for ion identification with very high resolution. It makes use of ion confinement in a Penning trap and, in contrast to methods applied to short-lived nuclides for precision mass determination, FT-ICR MS is a non-destructive detection technique, where the ions are still trapped after mass measurement and thus available for further studies. This property is of high interest for rare nuclides which are difficult to produce. The technique has not been used for high precision mass measurement on radionuclides at the level required for fundamental physics studies, but we are currently working on modifications to serve this purpose. Recent results from these studies at the Max-Planck-Institute for Nuclear Physics in Heidelberg, in particular the performance of a broad-band FT-ICR Penning trap system tested with 7Li+ ions in comparison with simulation and theoretical investigations, will be presented.
