Subjects of studies are:
-Physics of strong electromagnetic fields using highly charged ions studied by determination of transition energies. This will provide challenges to atomic theory and non-perturbative QED calculations. In addition, the hyper-fine structure in few-electron systems can be measured, to get information on the distribution of nuclear magnetism.
-Precision mass measurements in a Penning trap using a single but cold highly-charged ion are planned. The higher the charge, the higher will be the mass accuracy that is achieved. This requires cold, very highly charged ions to be transferred from S-EBIT to the precision Penning trap SMILETRAP
- Highly-charged ions on surfaces and nano-capillaries offer unique conditions due to the high yields of electrons per HCI because the potential energy of the ion is very large (around 100 keV) compared to its kinetic energy. New types of effects occur such as self-arranged in guiding in nano-tubes and nano-capillaries.
-Plasma spectroscopy from electron-ion processes is directly accessible through optical and x-ray windows at S-EBIT. Recombination rates and emission lines are of interest for fusion applications and for astro-physical plasma.

Responsible for the new ion trap/source will be the Physics Department/Division for Atomic Physics at Stockholm University. S-EBIT is conveniently mobile, it can, for example be moved to high-intensity laser laboratories, synchrotron or future VUV/X-ray free-electron laser (FEL) facilities. Combining the S-EBIT with an XUV-FEL will facilitate selective intense photon interaction with strongly bound electrons for the first time.
