Description
Super Cryogenic Dark Matter Search (SuperCDMS) SNOLAB is an experiment focused on searching for sub-10 GeV/c$^2$ dark-matter particles. The experiment utilizes two detector types. iZIP (interleaved Z-sensitive Ionization and Phonon) detectors have both ionization and phonon readout channels, providing excellent nuclear-recoil/electron-recoil discrimination. HV (High-Voltage) detectors apply a strong electric field across the detector to employ the NTL effect and enable dark-matter detection at masses below 1 MeV/c$^2$. The commissioned setup consists of 24 cryogenic semiconductor crystal detectors, including a mix of Ge and Si detectors. Accurate reconstruction of events in these detectors requires representative phonon pulse templates for use in optimal-filter processing. This work focuses on generating and validating channel-level and total-level templates for detectors using data collected during Run 2 at the SuperCDMS SNOLAB facility. This work supports the reliable estimation of event energy, position, and reconstruction quality, which are used for event selection and background rejection. The resulting event spectra can then be compared with signal and background models using a profile-likelihood-ratio analysis to search for evidence of dark matter.
