Creation of highly-charged calcium ions for the g-factor determination of the bound electron

High-precision measurements of the magnetic moment of the electron bound in hydrogen-and lithium-like ions can be used to test bound-state quantum electrodynamical calculations. In the past measurements with relative experimental uncertainties as low as 2x10-9 were performed on hydrogen-like carbon and oxygen ions. In the current experiment we plan to measure the g-factor of hydrogen-like and lithium-like calcium ions. A relative uncertainty δg/g in the order of 10-9 is aspired. Here, we will give the motivation for the experiment, present the experimental techniques and first results.
