In ARTEMIS (AsymmetRic Trap for measurement of Electron Magnetic moment in IonS), at HITRAP, we aim to perform the g-factor measurements of medium to heavy highly charged ions. It serves as a test of QED in strong fields and we do this using laser-microwave double-resonance spectroscopy. Currently, we are in the process of attaching the cold valve to ARTEMIS which will mark the completion of the beamline. This connects the experiment to the HITRAP facility and the EBIT, an offline ion source, and is on schedule for the planned beamtime of May 2022. Alongside this, in-situ production and analysis of Ar13+ ions are being successfully carried out (up to a few weeks). As of 2021, we have completed the individual assembly of the parts of the beamline connecting ARTEMIS to the HITRAP facility and have received ions in the final Faraday cup of the vertical beamline.
