We use a single ion as an movable electric field sensor with accuracies on\nthe order of a few V/m. For this, we compensate undesired static electric\nfields in a planar RF trap and characterize the static fields over an extended\nregion along the trap axis. We observe a strong buildup of stray charges around\nthe loading region on the trap resulting in an electric field of up to 1.3 kV/m\nat the ion position. We also find that the profile of the stray field remains\nconstant over a time span of a few months.\n
