Especially in experiments which aim at coupling Rydberg atoms to the near field of superconducting circuits, the identification and subsequent elimination of sources of stray fields is crucial. We present a technique that allows the determination of stray-electric-field distributions $(F^\\text{str}_\\text{x}(\\vec{r}),F^\\text{str}_\\text{y}(\\vec{r}),F^\\text{str}_\\text{z}(\\vec{r}))$ at distances of less than $2~\\text{mm}$ from (cryo","authors_text":"A.
