The SHIPTRAP Penning trap mass spectrometer has been designed and constructed to measure the mass of short-lived, radioactive nuclei. The radioactive nuclei are produced in fusion-evaporation reactions and separated in flight with the velocity filter SHIP at GSI in Darmstadt. They are captured in a gas cell and transferred to a double Penning trap mass spectrometer. There, the cyclotron frequencies of the radioactive ions are determined and yield mass values with uncertainties >=4.5·10
-8 . More than 50 nuclei have been investigated so far with the present overall efficiency of about 0.5 to 2%. [ABSTRACT FROM AUTHOR]- Published
