Description
DEAP-3600 is a single-phase dark matter detector that uses liquid argon scintillation to search for spin-independent weakly interacting massive particles (WIMPs).
Identifying background events is vital in WIMP searches due to the extremely small WIMP-nucleon interaction probability. To precisely model backgrounds, pileup—multiple interactions happening in a single event—must be understood. Pileup can be studied using our periodic trigger—a 40 Hz, threshold-less trigger—which provides snapshots of what is occurring in the detector at random moments.
One method to study pileup in DEAP-3600 is by mixing the raw waveforms of periodic trigger events with physics events.
