Measurements of electric field distributions in a low-pressure xenon discharge are presented. The measurement technique is based on Stark spectroscopy, using a 2 + 1 excitation scheme with fluorescence dip detection. Electric fields can be measured by detecting Stark shifts of high-lying Rydberg levels in xenon atoms. Quantification of electric field strengths is done by comparing experimental Stark shifts with theoretical calculations. The measurement technique is tested in the sheath of a xenon DC glow discharge.
