Description
Dual phase noble element detectors have demonstrated the strong ability to detect low energy ionization signals through strong electroluminescence in the gas. This amplifies the electron signal and makes the detection of individual electrons not only possible but also highly efficient. Two target nuclei, argon and xenon, are widely used in noble liquid detectors, with each having unique strengths and weaknesses. By doping percent level xenon into liquid argon, we have the potential to combine the benefits of argon and xenon in a single detector. In this talk, we discuss the most recent results from the CHILLAX experiment at LLNL, which operates a compact dual phase argon detector doped with percent level xenon in the liquid phase. We describe early measurements of the improvement to the electroluminescence signal as a function of increasing xenon concentration, as well as its potential benefits to dark matter and neutrino searches.
