Precision spectroscopy of xenon is relevant for a variety of applications, including searches for the neutron electric dipole moment and magnetometry. However, spectroscopy has been challenging due to the inaccessibility of suitable UV laser systems. We present a spectroscopy setup capable of performing two-photon spectroscopy of xenon, focusing on the 5p6 (1S0) → 5p5 (2P3/2)6p 2[5/2]2 transition at 256 nm. Building on earlier measurements of this transition, the setup incorporates the use of coincidence detection of emitted IR and UV fluorescence photons, which is expected to enhance the signal-to-noise ratio.
