The g factor of the electron bound in hydrogenlike 28Si13+ has been measured to 10 significant digits. The value agrees very well with bound-state quantum-electrodynamical calculations and represents to date the most stringent test of the theory. The experiment uses a single ion confined in a triple Penning trap. Here we present details of the setup, the experimental procedure and the data evaluation.
