SuperCDMS Experiment at SNOLAB: Current Status and Recent CUTE Results
The Super Cryogenic Dark Matter Search (SuperCDMS) experiment at SNOLAB explores dark matter candidates in the mass range of 1-10 $\mathrm{GeV/c^2}$. The experiment will deploy a total of 24 detectors with silicon and germanium substrates, 2 km deep underground in SNOLAB, Canada. The detectors are arranged in four towers, combining the low-threshold sensitivity of high-voltage (HV) phonon detectors with the excellent background discrimination of phonon-charge (iZIP)detectors. The combination will give SuperCDMS a world-leading edge in the search for low-mass, low-cross-section dark matter candidates. Over the past year, SuperCDMS completed testing a single HV tower at the Cryogenic Underground TEst facility (CUTE). The CUTE run, which concluded in February 2024, demonstrated the ability to conduct in-situ operations including characterization, calibration, and exploration of Neganov-Trofimov-Luke (NTL) phononamplification. This contribution will highlight key results from CUTE, along with the current status and prospects of the first SuperCDMS science run.
