1 The X Experiment - Background Model and Physics Goals D. Malling April APS, Denver, CO

2 X Background Goals Background goal: <1 WIMP-like event in 100 kg fiducial in 300 days Dominated by PMTs (material selection difficult, proximity to active region) Counting goals: ensure contributions from other materials subdominant to PMTs D. Malling April APS Denver, CO April 13,

3 X Backgrounds Program Monte Carlo Material Screening Generic ER Modeling for Small Internals Precision ER Modeling for Major Internals Precision NR Modeling for Major Internals In Situ Measurement S1/S2 Yields and Collection Efficiencies Activation Isotopes Predicted Low-Energy Background D. Malling April APS Denver, CO April 13,

4 non Backgrounds Require low-energy single-scatter nuclear recoil in central (100 kg) fiducial volume X PMT ER backgrounds (0-25 kevee) with unoptimized 100 kg fiducial (dashed) WIMP search energy window: 5-25 kevnr (1-5 kevee) Gammas required to traverse length of detector, deposit <5 kevee energy, exit again without scattering; suppression seen at right Another >2 orders of magnitude rejection of ER events based on S2/S1 ratio Neutron generation 1 n/day from radioisotopes; NR events rejected by multiple scatter signatures DRUee = cts/kevee/kg/day D. Malling April APS Denver, CO April 13,

5 Background Sources Internal components (PMTs, cryostats, panels, etc.) Managed primarily through material screening External radioactivity and muoninduced backgrounds External rates reduced to <x1/10 internal rates by 3.5 m thick water shield (300 tonnes) D. Malling April APS Denver, CO April 13,

6 Background Modeling All Monte Carlo modeling performed using Geant4-based XSim package [NIM A (2012)] Highly faithful X detector geometry -- allows for detailed studies of backgrounds from individual internals / radioisotopes Integrates NEST code for S1/S2 yields [JINST 6 p10002 (2011)] D. Malling April APS Denver, CO April 13,

7 Background Modeling Detailed ER / NR modeling performed for all large internals -- yields energy spectrum in detector as function of position, radioisotope concentration Generic activity library created to accommodate >100 small components -- whole regions of detector modeled with different radioisotopes Generic library sets required screening ULs, in addition to adding to total expected ER D. Malling April APS Denver, CO April 13,
