Light Collection Efficiency Simulation Average LCE in the target volume: 24%, 3.2 pe/keVee at zero field; nuclear recoil detection efficiency 100% at 5 keVr Average LCE in the active veto volume: 4.7% Relative LCE in the target volume, scaled to the maximum value in the target volume ( 137 Cs) (LCE) Alexander Kish | XENON100 | 14th Geant4 Users Workshop | Catania, Sicily | October 15, 2009 | p.10
Prediction of the Detected Light Yield in the Veto Volume Predicted LY in the top veto Predicted LY in the side veto Energy threshold in the active veto 5-100 keVee Fiducial volume and active veto cuts: up to 95-99% efficiency for electron recoil background rate reduction Further reduction by a factor of 100 with S2/S1 discrimination Alexander Kish | XENON100 | 14th Geant4 Users Workshop | Catania, Sicily | October 15, 2009 | p.11
