abstract: A precise measurement of bound-electron g factors in highly charged ions provides stringent tests for state-of-the-art theoretical calculations, such as relativistic electron-correlation, bound-state QED, and higher-order Zeeman effects. We excite the fine-structure transition of boronlike argon (40Ar13+) with laser radiation and probe microwave transitions between Zeeman sub-levels in the magnetic field of a Penning trap. From this laser-microwave double-resonance technique the g factor can be determined on a ppb level of accuracy in our apparatus. We have built a novel ’half-open’ Penning trap with high fluorescence-detection efficiency and an integrated electron-beam ion source for production of highly charged ions from gas, injected through a cryogenic valve. In the future, heavier ions shall be captured from the HITRAP facility at GSI and the method shall be applied to hyperfine-structure transitions of hydrogenlike bismuth (209Bi82+) in order to measure electronic and nuclear magnetic moments. This thesis presents experimental developments as well as production, cooling, transport, and long-term storage of highly charged argon ions.
