22nd SPARC Topical Workshop

The ARTEMIS experiment at the HITRAP facility situated at GSI, Darmstadt, focuses on precision spectroscopy of highly charged ions as a benchmark of QED in extreme fields. Electron magnetic moments (g-factor) will be determined using the laser-microwave double-resonance spectroscopy on the desired few-electron ions stored in the trap. Laser-microwave double-resonance spectroscopy enables...

On behalf of the SpecTrap collaboration, I will present the physics and status of the SpecTrap experiment located at the HITRAP facility at GSI, Germany. The aim of the experiment is optical and near-optical precision spectroscopy of highly charged ions that are confined and cooled in a dedicated Penning trap. Highly charged ions of interest comprise Bi82+ for further studies in the ARTEMIS...

Quantum logic spectroscopy (QLS) enables optical clocks based on atomic and molecular ions that lack direct laser cooling or state detection transitions [1]. QLS therefore serves as a key technique driving significant advances in optical frequency metrology [2-5]. Heavy hydrogen-like or lithium-like ions offer optical transitions that feature both strong suppression of systematic shifts and...
