In Penning traps electromagnetic forces are used to confine charged particles under well-controlled conditions for virtually unlimited time. Sensitive detection methods have been developed to allow observation of single stored ions. Various cooling methods can be employed to reduce the energy of the trapped particle to nearly at rest. In this review we summarize how highly charged ions (HCIs) offer unique possibilities for precision measurements in Penning traps. Precision atomic and nuclear masses as well as magnetic moments of bound electrons allow among others to determine fundamental constants like the mass of the electron or to perform stringent tests of fundamental interactions like bound-state quantum electrodynamics. Recent results and future perspectives in high-precision Penning-trap spectroscopy with HCIs will be discussed.

The absolute atomic mass of $$^{208}$$ 208 Pb has been determined with a fractional uncertainty of $$7\times 10^{-11}$$ 7 × 10 - 11 by measuring the cyclotron-frequency ratio R of $$^{208}$$ 208 Pb$$^{41+}$$ 41 + to $$^{132}$$ 132 Xe$$^{26+}$$ 26 + with the high-precision Penning-trap mass spectrometer Pentatrap and computing the binding energies $$E_{\text {Pb}}$$ E Pb and $$E_{\text {Xe}}$$ E Xe of the missing 41 and 26 atomic electrons, respectively, with the ab initio fully relativistic multi-configuration Dirac–Hartree–Fock (MCDHF) method. R has been measured with a relative precision of $$9\times 10^{-12}$$ 9 × 10 - 12 . $$E_{\text {Pb}}$$ E Pb and $$E_{\text {Xe}}$$ E Xe have been computed with an uncertainty of 9.1 eV and 2.1 eV, respectively, yielding $$207.976\,650\,571(14)$$ 207.976 650 571 ( 14 ) u ($$\text {u}=9.314\,941\,024\,2(28)\times 10^{8}$$ u = 9.314 941 024 2 ( 28 ) × 10 8 eV/c$$^2$$ 2 ) for the $$^{208}$$ 208 Pb neutral atomic mass. This result agrees within $$1.2\sigma $$ 1.2 σ with that from the Atomic-Mass Evaluation (AME) 2020, while improving the precision by almost two orders of magnitude. The new mass value directly improves the mass precision of 14 nuclides in the region of Z = 81–84 and is the most precise mass value with $$A>200$$ A > 200 . Thus, the measurement establishes a new region of reference mass values which can be used e.g. for precision mass determination of transuranium nuclides, including the superheavies.
