The ARTEMIS Experiment: Precision Spectroscopy of Highly Charged Ions in a Penning Trap — •Manuel Vogel1,2, Gerhard Birkl1, David von Lindenfels2,3, Alexander Martin1, Wolfgang Quint2,3, and Marco Wiesel1 — 1Institut für Angewandte Physik, TU Darmstadt, 64289 Darmstadt — 2GSI Helmholtzzentrum für Schwerionenforschung, 64291 Darmstadt — 3Physikalisches Institut, Ruprecht Karls-Universität Heidelberg, 69120 Heidelberg
We present the concept and setup of the ARTEMIS experiment located at the HITRAP facility at GSI, Germany. It is dedicated to laser-microwave double-resonance spectroscopy of confined and cooled highly-charged ions with high precision. Such spectroscopy allows a simultaneous determination of electronic and nuclear magnetic moments with respective relative accuracies on the ppb and ppm level. In single- and few-electron highly charged ions this opens the possibility to resolve QED contributions to the electron g-factor due to the bound state. At the same time, nuclear magnetic moments can be measured in absence of electronic shielding and corresponding models can be tested for the first time.
