Description
The Penning-trap mass spectrometer Pentatrap [1] located at the Max Planck Institute for Nuclear Physics in Heidelberg is performing mass-ratio measurements with a relative uncertainty in the 10^−11 regime. One of the unique features of the Pentatrap experiment is the external ion source producing a wide range of charge states from gaseous or solid-state samples down to only 10^15 atoms. the detection systems with single-ion sensitivity and the simultaneous measurements of two out of three eigenfrequencies in two adjacent traps.
Due to its versatility and high accuracy, Pentatrap can contribute to a variety of topics of fundamental physics. Among them are a test of bound-state QED in strong fields, a search for atomic long-lived metastable states in highly charged ions [2], and a search of dark matter by means of isotope shift spectroscopy. The setup overview and the latest results at Pentatrap will be presented.
