The DEAP-3600 experiment will search for dark matter particle interactions on 3.6 tonnes of liquid argon at SNOLAB. The argon is contained in a large ultralow-background acrylic vessel viewed by 255 8-inch photomultiplier tubes. Very good pulse-shape discrimination has been demonstrated for scintillation in argon, and the detector has been designed to allow control of (alpha,n) and external...

SuperCDMS searches for dark matter in the form of Weakly Interacting Massive Particles (WIMPs) using germanium detectors operated at a few tens of mK. Particles are detected via the change in resistance of a superconducting transition edge sensor heated by lattice vibrations (phonons) from the interaction. A bias voltage applied across the detector drifts electron-hole pairs produced in an...

More than eighty years after its existence was originally postulated, the search for Dark Matter is still ongoing. NEWS is a direct detection experiment that aims to detect WIMPs with a metallic spherical detector with a high voltage electrode in its centre, with gas as its target mass.
In the context of the NEWS experiment, our estimators of the energy of events, and their position within...

The search for dark matter calls for increasingly sensitive experiments. For several decades now, scientists have built more and more sensitive detectors in the hope to directly detect WIMPs, a type of candidate particles for dark matter. WIMPs should interact with normal matter by elastic scattering with nuclei. Experiments are typically performed underground to shield them from cosmic and...

The PICO experiment is a dark matter search using superheated liquid C$_3$F$_8$. The experiment operates two bubble chambers, PICO-2L and PICO-60, at the SNOLAB facility 2km underground, and is designed to be most sensitive to spin-carrying dark matter particles with a mass range of 10-10,000 GeV/$c^2$. PICO bubble chambers are threshold detectors that can be operated within a set of...
