The low-energy beam and ion trap facility (LEBIT), has been designed to facilitate a variety of experiments at low energies with rare isotopes produced by fast-beam fragmentation. Gas stopping of the fast-fragment beams and modern ion manipulation techniques are used. The first experiments to be performed are high-precision mass measurements possible with a 9.4 T Penning trap mass spectrometer. LEBIT has been recently commissioned and first experiments on stable and unstable nuclides have been performed. Here we present the results of mass measurements on stable krypton isotopes, measured with a precision of better than δm/m=5×10−8δm/m=5×10−8 that reveal significant deviations from the literature values for Kr83 and Kr84. The paper also provides an overview of LEBIT and the first Penning trap mass measurements performed on unstable isotopes from fast-beam fragmentation.
