The demand for beamtime at GSI facilities like ESR, CRYRING or HITRAP has increased over the last years and can not be fully covered by the GSI accelerator infrastructure. Local ion sources play an important role in closing this gap and allowing for *offline operation* of experiments at GSI.
Electron Beam Ion Traps (EBITs) are widely known as a versatile tool for spectroscopic studies of partially ionized atomic systems. Furthermore, they can be used as small stand-alone ion sources, capable of producing beams of heavy highly-charged ions of a certain charge state at reasonable intensities.
The S-EBIT II is currently under commissioning for operation as a facility for x-ray spectroscopy and as a standalone ion source for HITRAP. This will provide new opportunities for local experiments independently from the GSI accelerator infrastructure. Examples are the ARTEMIS experiment and the upcoming cryogenic paul trap for quantum logic spectroscopy. As a first step towards completing commissioning, we carried out DR measurements with argon.
