%X The main focus of this thesis is the development and characterization of new resonatorsfor the ARTEMIS (Asymmetric Trap for the measurement of ElectronMagnetic moment of Ions) experiment [1]. Resonators are a crucial part of anynon-destructive detection system implemented in Penning trap experiments likeARTEMIS [2].ARTEMIS is an experiment designed to perform precise measurements of themagnetic moment of bound electrons in heavy, highly charged ions [3]. Precisionmeasurements like these lead to more accurate fundamental constants and are anexcellent test of quantum electrodynamics. The recent discovery of the g-2 discrepancyfor muons at Fermi lab showed the importance of these precision measurements[4].An integral part of the ARTEMIS g-2 experiment is the measurement of thecyclotron frequency. In a Penning trap, the cyclotron frequency can be measuredusing detection systems. A resonator is tuned to the oscillation frequency of the9ions and the resulting signal is then amplied and evaluated. The Quality factor ofthe resonator determines precision of this measurement, and is therefore a key focusfor a Penning trap experiment.Recent measurements of the currently used resonators have indicated that theyhave a dierent Q-value when used inside of the ARTEMIS experiment than measurementswith a test stand suggested. To test this hypothesis and to improvethe Q-value leading to more precise results, new resonators needed to be built andcharacterized.These resonators were tested at room temperature and in cryogenic conditions.The test was done using the test stand setup which is outside the experiment.Measurements with the previously used resonators in the ARTEMIS experimentwere also taken, to produce comparable data. These data should later be comparedto similar measurements done using the new resonators to determine the Q-factorand the characteristics inside of ARTEMIS.
