Using Virtual Reality to Visualize the Interactions of WIMPS in a Liquid Xenon Time Projection Chamber

Direct dark matter detection experiments employ noble element time projection chambers (TPCs) to search for weakly interacting massive particles (WIMPs). This project models the liquid xenon CaliX prototype TPC, designed by the Kamaha group at UCLA using the standard GEANT4 simulation framework. The Noble Element Simulation Technique (NEST) was utilized with GEANT4 to model low-energy thermal electrons accurately and to produce correct electron and photon yields for electron recoil (ER) and nuclear recoil (NR) events. Runs were conducted with neutron sources to replicate calibration sources used by the Kamaha group, and the simulated data were compared with previous experimental results, validating the physical accuracy of the model. To enhance visualization, events were observed in virtual reality (VR) using the G4VR app, enabling interactive observation of energy depositions, particle trajectories, and time evolution. Ongoing work involves testing additional calibration sources with this detector geometry and modeling WIMP interactions in VR.
