The high-precision Penning-trap mass spectrometer Pentatrap [1] is being commissioned at the Max-Planck-Institut für Kernphysik in Heidelberg. We are aiming at mass ratio measurements of stable and long-lived highly charged ions with relative uncertainties of 10−11. This allows, among others, contributions to neutrino physics research, i.e. the mass difference of the mother and daughter nuclide of the electron capture decay of 163Ho to 163Dy or a direct test of special relativity [2], i.e. via the mass difference of the mother and daughter nuclide of the neutron capture in 35Cl to 36Cl. After a revision of the cryogenic setup and the ion transfer beamline we have recently trapped the first single ion in our trap system, demonstrated transport between traps and showed full control over the three eigenmotions by means of resonant dipolar and quadrupolar radiofrequency excitations.
This contribution will report on the experimental setup and current to near future measurements at Pentatrap.
