Detection and discrimination of low energy electronic and nuclear recoils with a single-phase liquid xenon detector

The Liquid Xenon Proportional Scintillation Counter (LXePSC) is a single-phase liquid xenon detector capable of producing electroluminescence directly in the liquid phase. In doing so, we are able to achieve a 100% extraction efficiency and simplify the detector design and operation by not needing to maintain a stable gas-gap of a few mm, as is the case in dual-phase Xe TPCs. In this talk, we will present our recent results which show that the LXePSC is capable of detecting both nuclear and electronic recoils down to ~1 keV and discriminate between them. Applications of such type of single-phase detectors will be discussed.
