Description
Liquid phase xenon electroluminescence allows us to achieve a perfect extraction efficiency by eliminating the liquid-gas interface, at the cost of having a low single-electron gain. For low-energy searches, we are concerned with the discrimination between electronic and nuclear recoils (ER and NR), as well as the single-electron background. In this talk, we shall show evidence that ER/NR discrimination can be maintained even with a low single-electron gain, but that the single-electron background following a large ionization signal is still present and characteristically similar to that of the dual phase xenon TPCs.
