Fig. 3: Simulated energy thresholds for Xe and H recoils in LXe.
From: HydroX, a light dark matter search with hydrogen-doped liquid xenon time projection chambers

The thresholds are calculated using NEST and the full detector simulation described in ref. 87 and shown for both a standard S1/S2 analysis, requiring an S1 signal in 3 photomultiplier tubes, as well as for an S2-only analysis, requiring 3 detected electrons.
