One of the precision experiments of the HITRAP facility at GSI Darmstadt is SpecTrap, which aims to trap heavy Highly Charged Ions (HCI) in a Penning trap and cool them to cryogenic temperatures. Using laser spectroscopy it is possible to measure their hyperfine structure with an envisaged relative accuracy of the order of 10−7 which will serve as a test of strong-field quantum electrodynamics.
This poster will present the current status of the SpecTrap experiment and give an overview of the associated beamline from the Electron Beam Ion Source (EBIS) to the Penning trap. The EBIS can produce HCI up to Xe44+ and the beamline is able to transport these ions with small kinetic energy with a few keV to SpecTrap or other experimental setups. Additionally the methods and first experimental results for detecting, cooling and manipulating the ions inside the trap will be shown.
