The high-precision Penning-trap mass spectrometer Pentatrap [1] located at the Max-Planck-Institut für Kernphysik in Heidelberg is aiming at mass ratio measurements of stable and long-lived highly charged ions with relative uncertainties of 10−11, or better. This allows, among others, contributions to neutrino physics research, e.g. by the mass difference measurement of the mother and daughter nuclide of the electron capture decay of 163Ho to 163Dy [2] or a direct test of special relativity [3], e.g. via the mass difference of the mother and daughter nuclide of the neutron capture in 35Cl to 36Cl. With its first proof-of-principle measurements Pentatrap has recently demonstrated a relative mass precision of 3·10−11 to determine absolute masses and electron binding energies of highly charged ions of different xenon isotopes in different charge states. The talk will present the experimental setup and current to near future measurements at Pentatrap.
