The first stage is SourceSim, composed of a number of subcomponents known as SuperSim, and WimpSim.The core component does the simulation of the particle-level interactions, from the source to the crystal, called SuperSim. It is based on a standard particle physics package called Geant4 which simulates particle interactions and propagation within materials. For the simulations of WIMP interactions (since non-SM interactions are not part of Geant4), we use a custom package known as WimpSim which simulates signal-like events following the astrophysical implications (note that this functionality has been integrated into SuperSim, after the analysis presented in this thesis). The final output, after any post-processing to select-out subsets of events (as shown in the Postprocessing box for completeness), contains all the information needed by DetectorSim including the particle interactions in the detector crystal (whether electron or nuclear recoils), the amount of energy deposited, and the location where the interaction occurred. We note that a single particle can interact multiple times within a detector, called multiple scatters. The information for all scatters are put in an output file called ParticleHits. The detector readout response simulation is performed by DetectorSim, which simulates the charge and phonon creation, as well as their propagation through the crystal and all collection by the sensors. How iZIP simulation show better electron and nuclear band gap than HV detectors? Specify the dark matter limit for both these detectors.
