"The high-precision Penning-trap mass spectrometer Pentatrap was designed to perform\r\nmass-ratio measurements of highly charged ions with relative uncertainties of 10−11. The\r\nunique features of the Pentatrap experiment are the external ion sources providing\r\nhighly charged ions, the detection systems with single-ion sensitivity and especially the\r\nstack of five Penning traps, which allows simultaneous measurements of single ions in\r\nthe traps. In the scope of this thesis, the first high-precision mass measurements with a\r\nrelative precision partially below δm/m ≈ 10−11 were performed. As a first benchmark\r\n\r\ntest, the mass differences of five xenon isotope pairs were determined. Comparison to\r\nthe literature values led to an improvement of the uncertainty of the mass differences of\r\na factor between 4 and 1700, in agreement with literature. In order to demonstrate the\r\naccuracy of Pentatrap, the binding energy of the 37th electron in 132Xe was determined\r\nas a proof-of-principle measurement by determining the mass difference of 132Xe17+ and\r\n132Xe18+. The agreement of the result with theory allows performing stringent tests of\r\nquantum electrodynamics using binding energies in ions with an even higher charge state\r\nin the future. Lastly, the discovery of metastable electronic states in highly charged rhe-\r\nnium and osmium ions by mass difference measurements, confirmed by theory, extends\r\nthe applicability of Penning-trap mass spectrometry to tests of atomic structure theories\r\nand to the identification of long-lived excited states for a possible new generation of clocks\r\nusing highly charged ions."^^ .
