The Super Cryogenic Dark Matter Search (SuperCDMS) direct detection experiment focuses on the search for low-mass (< 10 GeV/$c^{2}$) dark matter particles. It is currently being installed 2 km underground at SNOLAB, Canada. The payload will consist of 24 cryogenic germanium and silicon detectors arranged in four towers with six detectors each. The detectors come in two varieties, called HV and...
The Super Cryogenic Dark Matter Search (SuperCDMS) collaboration uses cryogenic silicon and germanium detectors to search for evidence of dark matter. The collaboration utilises Monte Carlo simulations to examine the predicted response of these detectors to energy depositions by dark matter particles via nuclear recoil. The detectors produce signals through creation of electron-hole pairs...
The NEWS-G collaboration uses spherical proportional counters to search directly for low-mass dark matter. Each counter is a metallic sphere filled with gas with high-voltage anodes at its centre producing a radial electric field. The interaction between a dark matter particle and a nucleus can ionize the gas, which leads to electron avalanches near the anodes and a detectable signal. The...
The Scintillating Bubble Chamber (SBC) collaboration combines historic bubble chamber technologies with the scintillation properties of liquid nobles to create a detector uniquely suited to low threshold rare event searches. The collaboration has built two nearly identical assemblies, SBC-LAr10 is meant for calibration studies and future coherent elastic neutrino-nucleus scattering research at...
The Light-only Liquid Xenon (LoLX) experiment operates at McGill University in collaboration with TRIUMF. The experiment uses silicon photomultipliers (SiPMs) to examine liquid xenon (LXe) scintillation characteristics for detecting rare physical events, such as neutrinoless double beta decay or dark matter. The primary goals are to understand SiPM performance and study LXe scintillation...
DEAP-3600 is a single-phase liquid argon detector designed to probe for high mass WIMP dark matter candidates. A global collaboration, DEAP has previously run from 2016 to 2020 in the Cube Hall at SNOLAB. From extensive background modeling a small background rate was expected in the WIMP region of interest. These events were predicted to originate in two ways: Either shadowing caused by the...
