Systematic Effects of a Gaseous Argon Detector for Anti-Neutrino Scatters

Dual-phase, noble-element detectors are a useful choice for searching for coherent neutrino scatters, given their low energy threshold and electron transport properties. We have constructed a single-phase argon detector to study the systematics of the gaseous region of a planned dual-phase detector, as well as to measure the nuclear quenching factor of gaseous argon at a nuclear recoil energy of 8 keV. We will report on our progress to improve the signal from our single-phase detector, including verification of our optical response model, gas purification, fiducialization of the active volume, and anticipated gas content at cryogenic temperatures.
