Description
The Super Cryogenic Dark Matter Search (SuperCDMS) SNOLAB is a direct detection dark matter (DM) experiment located 2 $\mathrm{km}$ underground at the SNOLAB facility near Sudbury, Canada. The experiment consists of 24 cylindrical kilogram-scale Germanium and Silicon detectors with Transition Edge Sensors (TESs) masks instrumented on the top and bottom surface. The unique mix of target substrates and detector technologies will allow SuperCDMS to probe the Weakly Interacting Massive Particle (WIMP) nuclear recoil DM parameter space with world-leading sensitivity in the mass range from 0.5 to 5 $\mathrm{GeV/c^2}$. SuperCDMS is currently in the commissioning phase and the first science run is expected to begin by mid-2026. From October 2023 to March 2024, the detectors in one of the four detector towers were characterized at the Cryogenic Underground TEst facility (CUTE), which is also located at SNOLAB. The DM sensitivity of the experiment depends on the position and energy resolution of the detectors. Therefore, correlated noise and pulse shape variations must be properly accounted for during the data processing. The SuperCDMS collaboration developed its own event reconstruction algorithm, $\mathrm{NxM}$, that simultaneously fits $\mathrm{N}$ detector channels with $\mathrm{M}$ pulse templates and is mathematically formulated to treat these effects. These improvements were tested on the data collected during CUTE tower test. This poster will introduce the algorithm, and show the results of its application to the data obtained at the CUTE facility.
