Description
Located 2km underground at SNOLAB, the SuperCDMS (Cryogenic
Dark Matter Search) experiment will focus on the detection of low-mass
(<10 GeV/c2) dark matter particles. The experiment utilizes 6 silicon and
18 germanium cryogenic calorimeters arranged in 4 detector towers.
There are two types of individual detectors; HV and iZIP. The HV detectors
are instrumented with phonon sensors, and are operated at a high voltage
(100V) to take advantage of the Neganov-Trofimov-Luke effect and
achieve a lower threshold. In addition to the phonon sensors, the iZIP
detectors have charge sensors, which allow for event-by-event particle
discrimination. Commissioning is expected to begin in late-2025, with the
first science run occuring in early 2026. This talk will provide an overview
of the SuperCDMS experiment, detail its main science goals and key
results from a recent testing of an HV detector tower inside the Cryogenic
Underground TEst (CUTE) facility at SNOLAB. Additionally, the talk will
present recent results from the HVeV (High-Voltage eV-resolution)
detector R&D efforts, which recently achieved a sub-eV baseline
resolution.
