Measurements with the Penning-trap mass spectrometer Pentatrap [1], located at the Max-Planck-Institut für Kernphysik in Heidelberg, allow to determine mass ratios with a relative uncertainty in the few parts per trillion regime using highly charged ions [2]. Pentatrap’s mass measurements of selected nuclides allow, among others, to contribute to tests of special relativity, bound-state quantum electrodynamics and neutrino-physics research. Achieving this level of precision requires using a cryogenic image-current detection system with single-ion sensitivity and phase-sensitive detection methods in combination with highly charged ions provided by external ion sources. The talk will present recent measurement results on neon for tests of bound-state quantum electrodynamics as well as medium heavy isotopes of ytterbium for dark matter search [3].
