The ARTEMIS experiment at the HITRAP facility situated at GSI focuses on precision measurement of electron magnetic moments in highly charged ions as a benchmark of QED in extreme fields. The resistively cooled ions are detected using non-destructive techniques, followed by laser-microwave double-resonance spectroscopy on the desired few-electron heavy ions in a cryogenic Penning trap. The high magnetic fields leading to higher order Zeeman effects provide different outlooks to the theory of quantum electrodynamics for an atomic nucleus. The system has been commissioned with ions produced internally and is now being upgraded to dynamic capture and storage of ions produced from external sources like EBITs and the HITRAP facility. We present the current status of the experiment and recent results on ion cooling.
