Neutrino detectors

• SNO+ is a neutrino experiment using the original SNO experiment chamber, but using liquid scintillator in the place of heavy water from SNO. Linear alkyl benzene, the scintillator, increases the light yield, and therefore the sensitivity, allowing SNO+ to detect not only solar neutrinos, but also geoneutrinos, and reactor neutrinos. The ultimate goal of SNO+ is to observe neutrinoless double beta decay (0vbb).
• HALO (Helium and Lead Observatory) is a neutron detector using ring-shaped lead blocks to detect neutrinos from supernovae within our galaxy.^[13][14] HALO is part of the Supernova Early Warning System (SNEWS), an international collaboration of neutrino-sensitive detectors that will allow astronomers the opportunity to observe the first photons visible following a core-collapse supernova.^[15]

Dark matter detectors

• DAMIC - Dark Matter in Charged Coupled Devices (CCDs) – a dark matter detector using unusually thick CCDs to take long exposure images of particles passing through the detector. Various particles have known signatures and DAMIC seeks to find something new that could signal dark matter particles.^{[16][17][18][19]}
• DEAP-3600 - Dark Matter Experiment using Argon Pulse-shape Discrimination - is a second generation dark matter detector, using 3600 kg of liquid argon. This experiment aims to detect WIMP-like dark matter particles through argon scintillation, producing small amounts of light that is detected by extremely sensitive photomultiplier tubes.^[20][21][22]
• The PICO 40L, a third generation bubble chamber dark matter search experiment,^[10][23] is a merger of the former PICASSO and COUPP collaborations.^[24][25] PICO operates using superheated fluids which form small bubbles when energy is deposited by particle interactions. These bubbles are then detected by high speed cameras and extremely sensitive microphones.^[26]

Biological experiments

• FLAME – Flies in A Mine Experiment – a biological experiment using fruit flies as a model organism to investigate the physical responses to working in increased atmospheric pressure underground.^[27]
• REPAIR – Researching the Effects of the Presence and Absence of Ionizing Radiation – a biological experiment investigating the effects of low background radiation on growth, development, and cellular repair mechanisms.^[28]

Projects under construction

• SuperCDMS - Super-Cryogenic Dark Matter Search - is a second generation dark matter detector using silicon and germanium crystals cooled down to 10 mK, a fraction of a degree above absolute zero. This experiment aims to detect low mass dark matter particles through very small energy deposition in the crystal from particle collisions, resulting in vibrations detected by sensors.^{[29][30][31][32]}
• NEWS-G - New Experiments with Spheres–Gas – is a second generation spherical proportional counter electrostatic dark matter detector using noble gases in their gaseous state, as opposed to liquid noble gases used in DEAP-3600 and miniCLEAN. The original NEWS experiment is at the Laboratoire Souterrain de Modane.^[33][34]

Decommissioned experiments

• The original heavy water based Sudbury Neutrino Observatory experiment,
• The POLARIS underground project at SNOLAB (PUPS), observing seismic signals at depth in very hard rock,
• The first-generation COUPP 4-kg bubble chamber dark matter search,^[35][36][37] is no longer in operation.^[38][39]
• The DEAP-1 dark matter search,^[38][37] and
• The PICASSO dark matter search.^[40][4]
• MiniCLEAN (Cryogenic Low-Energy Astrophysics with Noble gases) dark matter detector,^{[10]: 24–32}

Future projects

Additional planned experiments have requested laboratory space such as the next-generation nEXO,^{[41][42][23][43][24]} and the LEGEND-1000 ^[44][45] searches for neutrinoless double beta decay.^[38][40] There are also plans for a larger PICO-500L detector.^[46]

The total size of the SNOLAB underground facilities, including utility spaces and personnel spaces, is:^[47][48]
