The TUCAN EDM experiment aims to measure the neutron electric dipole moment (EDM) to a precision of $1\times 10^{-27}~e$cm, by making a precise measurement of the neutron precession frequency change in a parallel magnetic and electric field when the eletric field direction is inverted. To make this measurement a coil will be used to provide a homogeneous precession magnetic field of...

The Cryogenic Underground TEst Facility (CUTE) is fully operational in the low-radioactivity environment of the SNOLAB Underground Laboratory. Estimation of the background from radioactive processes via Geant4 simulation is crucial in informing the background budget for the facility. The radioactive background characterization of the CUTE facility will be presented along with the background...

DEAP-3600 is a single-phase liquid argon (LAr) direct dark matter search experiment. DEAP uses a LAr target to search for weakly interacting massive particles (WIMPs), a prime candidate for dark matter. The LAr is contained within an acrylic vessel surrounded by 255 photomultiplier tubes in order to detect scintillation light.
Background characterization for events that might mimic a WIMP...

This overview talk will feature the latest results from DEAP-3600, including world-leading constraints on Planck-scale mass dark matter. Located at SNOLAB, 2 km underground in Sudbury, Ontario, the DEAP-3600 experiment consists of 3.3 tonnes of liquid argon in a large acrylic cryostat instrumented with 255 photomultiplier tubes. The broad physics programme of DEAP-3600 will be presented,...

The NEWS-G experiment employs Spherical Proportional Counters (SPC) towards the direct search for light Dark Matter candidates in the 0.1 – 10 GeV mass range. The detector provides high sensitivity to low-energy recoil detection thanks to the choice of various gases and operating pressures. In addition, the sensitivity is enhanced by the properties of the central anode where the avalanche...

The Light-only Liquid Xenon (LoLX) experiment has been developed to study the properties of light emission and transport in liquid xenon (LXe) using 96 Hamamatsu VUV4 SiPM modules. LoLX is also being used to investigate the timing structures of scintillation and Cherenkov light production in LXe and provide a better understanding of the effects of external cross-talk between neighbouring SiPM...
