The mass of particles is a fundamental property, and its precise determination allows contributions to be made to a wide variety of areas in atomic and nuclear physics. The most accurate mass measurements are achieved with individual, highly charged ions in a Penning trap, where relative accuracies of 10-12 are achieved. Such measurements are used in the search for new physics (Phys. Rev. Lett. 134, , determining the neutrino mass (Nature Physics 20, 921– )), and determining excited states in the atomic shell (Nature 581, 42– )).

However, high-precision mass measurements have so far been limited to light and medium-heavy ions or medium charge states. A Helmholtz Investigator Group has therefore been established at the Helmholtz Institute Jena, with an experimental site at GSI in Darmstadt, to extend this technology to the heaviest ions in the highest charge states and, among other applications, perform precise tests of quantum electrodynamics in strong fields. At GSI, such ions can be generated using the heavy ion accelerator and, after a deceleration process, made available for ion trap experiments – a worldwide unique combination of experimental infrastructure. xvbsvpc To strengthen the Helmholtz Investigator Group, set up the Penning trap mass spectrometer and carry out future measurements, we are looking for a PhD Student to start as soon as possible.
