The ARTEMIS Penning trap will use laser-microwave double-resonance spectroscopy to measure the intrinsic magnetic moments of both electrons and nuclei in heavy, highly charged ions (HCIs). The (hyper)fine and Zeeman transitions of such HCIs in ARTEMIS are in the optical or microwave regimes respectively. A closed optical cycle probes successful induction of spin flips by microwave stimulus.
The spectroscopy trap of ARTEMIS uses a half-open design with a transparent, conductive endcap. This enables ≈2 sr conical access to the trap center for irradiation and detection of fluorescent light. This is more than an order of magnitude greater than conventional cylindrical designs with similar harmonicity and tunability. On the opposite side, cooled ion bunches are injected from an adjacent trap, where they are created by electron impact ionization.
Currently, ARTEMIS is working on systematics measurements with boron-like Ar13+ and preparing for capture of heavy HCIs such as hydrogen-like Bi82+ from the HITRAP facility at GSI.
