Deep underground environments expose humans to environmental conditions whose physiological effects remain almost entirely unstudied, despite their relevance to mining, remote operations, and extreme environment medicine. POLAR (Physiology Of Life in Austere Regions) is using portable ultrasound technology at SNOLAB to capture the first real-time measurements of human cardiac and pulmonary...

DEAP‑3600, with its 3.3‑tonne target and located at SNOLAB, currently represents the leading effort within the international community in the dark‑matter direct detection in liquid argon, while construction of the next‑generation experiment, DarkSide‑20k, is underway at LNGS in Italy. By analyzing approximately three years of data, DEAP‑3600 has recently released its most up-to-date exclusion...

The XLZD Collaboration is developing an international experiment to search for WIMP dark matter down to the systematic limit imposed by astrophysical neutrinos and to search for neutrinoless double beta decay with a sensitivity competitive to other next-generation searches. Earlier this year a Canadian team of 18 scientists at 11 institutions joined these efforts with the goal of attracting...

Internal calibration sources used in SNO+ have been deployed last year (2025). In order to maintain the quality of the liquid scintillator in the SNO+ Acrylic Vessel (AV), calibration sources must be cleaned and confirmed to be at the desired cleanliness level for SNO+ scintillator. A bespoke Source Cleaning Vessel (SCV) was developed for this task, recirculating a closed-loop volume of SNO+...

The SNO+ experiment is built into the large cavern at SNOLAB, it consists of a central 12 meter diameter acrylic sphere filled with scintillating cocktail linear alkyl benzene and wavelength shifting fluors surrounded ~9400, 8 inch PMTs held in place by a geodesic support structure. The physics goals of the experiment focus on several aspects of neutrino physics, from solar, reactor and...

SNO+ is a multi-purpose neutrino detector based at SNOLAB with the capability to make contributions to multi-messenger astronomy. The majority of recent attention has been focussed on the observation of reactor neutrino oscillations and novel solar neutrino measurements. In addition to these measurements, SNO+ has explored the environment around SNOLAB itself with the detection of...

Muons, while reduced at SNOLAB's underground complex, are still a dominant background to many of the experiments located there. Two new collaborations are interested in better understanding these muon shower interactions: COSMO and CRUST. COSMO is a hardware project with industry partners, looking to deploy muon trackers in different locations underground, for a ~decadal study of the...

The SuperCDMS SNOLAB experiment, having concluded its Installation & Integration phase in January, is currently in its Commissioning phase. Early commissioning data, combined with data from the testing of one detector tower in CUTE in Fall 2023, is informing detector characterization, background modeling, calibration schemes, and event reconstruction techniques. This talk will summarize the...

In direct detection searches for scattering of electrons off low-mass (sub-GeV) DM, a promising approach to address problematic backgrounds and penetrate the "neutrino fog" is to exploit Earth’s daily rotation relative to the direction of the DM wind, which can result in a modulation of the expected signal rate. Organic scintillating crystals contain an intrinsic anisotropy in their...

Neutrinoless double beta decay (0νββ) is a hypothetical nuclear process in which two neutrons in a nucleus transform into two protons and two electrons without emitting electron antineutrinos. Its observation would demonstrate lepton number violation in weak processes and confirm that neutrinos are Majorana particles. Next-generation 0νββ searches using candidate isotopes aim to reach...

We discuss the recent result of DEAP-3600 showing evidence for charged-current Boron-8 solar neutrino absorption on Argon-40. In a visible energy window corresponding to neutrino energies of 12.0 to 14.5 MeV, we observe 6 candidate events. This measurement is of 4.0 sigma significance, and corresponds to a cross section a factor of (2.4 +1.3 -1.0) times that of Bhattacharya, Goodman, and Garcia (2009).

Characterizing ambient neutron backgrounds is vital for mitigating background with shielding in deep underground rare-event physics searches. We present an experimental and analytical framework to reconstruct the ambient neutron flux up to 11 MeV at the SNOLAB J-Drift location using repurposed Helium-3 (He-3) Neutral Current Detectors (NCDs). First, a direct thermal neutron flux measurement...

Multi-messenger astronomy is a flourishing field that seeks to combine signals from many experiments to characterize astrophysical objects and events. These experiments use a huge number of technologies to observe different intermediary particles such as visible, radio-frequency, and X-ray photons; cosmic rays; neutrinos; and gravitational waves. The key to combining these diverse experiments...

Natural background radiation (NBR) has been a constant environmental force throughout the evolution of life, yet its contribution to normal human tissue function remains poorly understood. The REPAIR project, located 2 km underground at SNOLAB, provides a unique ultra-low radiation environment where we can investigate how biological systems respond when this longstanding environmental signal...

Cosmogenic muons are a major background source in rare event search experiments. To mitigate this background, neutrinoless double beta decay (0νββ) and direct detection dark matter experiments prefer to operate in deep underground laboratories, where they can receive adequate shielding from cosmic rays. However, high energy muons can still reach underground and create backgrounds for these...

HALO, the Helium and Lead Observatory, has been operating at SNOLAB for fourteen years as a low-maintenance, high-livetime supernova neutrino detector. The HALO detector is principally composed 79 tonnes of lead from a decommissioned cosmic ray station, and is instrumented by 368 m of SNO’s ultra-low activity He-3 neutron counters. Supernova neutrinos interacting with the lead target may...
