Liquid xenon (LXe) is a well-studied detector medium to search for rareevents in dark matter and neutrino physics. Two-phase xenon time projectionchambers (TPCs) can detect electronic and nuclear recoils with energy down tokilo-electron volts (keV). In this paper, we characterize the response of asingle-phase liquid xenon proportional scintillation counter (LXePSC), whichproduces electroluminescence directly in the liquid, to detect electronicrecoils at low energies. Our design uses a thin (10 - 25 $\mu$m diameter),central anode wire in a cylindrical LXe target where ionization electrons,created from radiation particles, drift radially towards the anode, andelectroluminescence is produced. Both the primary scintillation (S1) andelectroluminescence (S2) are detected by photomultiplier tubes (PMTs)surrounding the LXe target. Up to 17 photons are produced per electron,obtained with a 10 $\mu$m diameter anode wire, allowing for the highlyefficient detection of electronic recoils from beta decays of a tritium sourcedown to roughly 1 keV. Single electrons, from photo-emission of the cathodewires, are observed at a gain of 1.8 photoelectrons (PE) per electron. Thedelayed signals following the S2 signals are dominated by single-photon-likehits, without evidence for electron signals observed in the two-phase xenonTPCs. We discuss the potential application of such a LXePSC for reactorneutrino detection via Coherent Elastic Neutrino Nucleus Scattering(CE$\nu$NS).
