HITRAP Facility and Experiments - Status and Future Perspectives

SpecTrap is part of the experiments located at HITRAP and aims at precision measurements of optical transitions in few-electron highly charged ions as a means of testing QED predictions in the regime of extreme electromagnetic fields. Particularly, focus is on spectroscopy of hyperfine transitions in hydrogen- and lithium-like ions that are cooled and confined in the cryogenic Penning trap. I...

The Jena Atomic Calculator (JAC) provides an easy-to-use but powerful toolbox to extent atomic theory towards new applications. It has been designed to be equally accessible for working spectroscopists, theoreticians and code developers. In this talk, I shall discuss the recent progress in developing these tools towards different cascade and second-order processes which are relevant for...

Precision isotope-shift spectroscopy of ions provides a very promising tool to probe the fundamental limits of Standard Model and to search for hypothetical "fifth-force" interactions. The analysis of the isotope-shift experimental and theoretical results can be performed most conveniently by means of the so-called King plot (KP). In this plot, the normalized frequency shifts of two (or even...
