The ARTEMIS experiment at the HITRAP facility situated at GSI focuses on precision measurements of electron magnetic moments in highly charged ions. Ions are currently produced inside the cryogenic Penning trap of the experiment [Kanika et al., J. Phys. B 56, 175001 (2023)] and are prepared and cooled using non-destructive techniques [Ebrahimi et al., Phys. Rev. A 98, 023423 (2018)]. Electron magnetic moments (g-factor) will be measured using the laser-microwave double-resonance spectroscopy on the desired few-electron ions stored in the trap. The connection to the HITRAP beamline and upgrades for dynamic capture and storage of ions from external sources enables this method to be applied to hydrogen-like heavy species such as Bi82+ and other lighter species such as S11+. The half-open design of the trap allows optical access which in turn facilitates microwave probing of the Larmor frequency through laser spectroscopy of fine/hyperfine structure of the ions. We present the current status of the experiment.
