Broad-Band FT-ICR MS for the Penning-Trap Mass Spectrometer MATS.

Ion traps are known as ideal tools for precision measurements of fundamental particle properties. In particular, traps have been set up at Radioactive Ion Beam (RIB) facilities to investigate exotic nuclei. During the last decade this field of research has constantly grown, with currently almost a dozen ion-trap systems at RIB facilities in Europe and North America and several more planned at future accelerators projects. One of these, the Advanced Trapping System MATS will be installed at the low-energy branch for radioactive-ion beams at the Facility for Antiprotons and Ion Research (FAIR) in Darmstadt (Germany). One of the MATS features will be non-destructive ion detection based on Fourier-Transform Ion-Cyclotron-Resonance Mass Spectrometry (FT-ICR MS). A prototype of the system has been developed at the Max-Planck-Institute for Nuclear Physics in Heidelberg (Germany) and recent results are outlined in this contribution. [ABSTRACT FROM AUTHOR]
