We present the preliminary design of the Argon Ultra‑Radiopure Observatory for Rare‑event Analysis (AURORA), a proposed experiment using doped argon and targeting dark matter in the sub‑GeV mass range. The experiment will feature a dual-phase time projection chamber (TPC) instrumented with digital silicon photomultipliers and filled with argon mixed with a few ppm of dopants, such as xenon,...

As an offshoot of the main SuperCDMS (Cryogenic Dark Matter Search) experiment, smaller instruments dubbed HVeV (high-voltage, electronvolt-scale resolution) detectors have been under continuous development to aid in the search for dark matter at masses below 1 MeV/c², achieving a much finer energy resolution than SuperCDMS. Similar to the SuperCDMS HV detectors, HVeV detectors hold silicon...

Oral (Non-Student) / Orale (non-étudiant(e))

SuperCDMS is a direct detection dark matter experiment located 2 km underground at SNOLAB, designed to have particular sensitivity to the dark matter mass region <10 GeV/c2. In order to claim discovery or set new limits on dark matter properties such an experiment must have a detailed understanding of the backgrounds expected at the facility, the response of the detectors to these backgrounds,...

800. In Situ Comparison of Silicon Photomultiplier Performance in Liquid Xenon with LoLX 2

Oral (Non-Student) / Orale (non-étudiant(e))

Liquid xenon (LXe) based detectors are a leading technology for low-background searches, including dark matter and neutrinoless double beta decay detection. Improving the sensitivity of next-generation experiments requires further reduction of radioactive backgrounds from detector components, motivating silicon photomultipliers (SiPMs) as a leading candidate to replace widely used...

SuperCDMS is a direct detection dark matter (DM) experiment which is currently in its commissioning phase at the SNOLAB underground laboratory in Sudbury, Canada. It operates cryogenically cooled Ge and Si crystals with different sensor designs to perform a broadband DM search for particles with masses $\le 10\, \text{GeV}/c^2$, thereby exploring new regions of parameter space.
