SNOLAB is an epicenter of global astroparticle physics and underground science discovery and research. As one of the deepest, cleanest underground laboratory in the world, with first-rate scientists and staff, it is a location of choice for cutting edge experiments. In this talk I will highlight some of the exciting research conducted at SNOLAB and discuss potential future research directions.

The SuperCDMS SNOLAB experiment is a next-generation direct detection dark matter search experiment with an anticipated world-leading sensitivity to particles with masses $\leq 10 \text{ GeV/c}^2$. The experiment is currently under construction at SNOLAB in Sudbury, Ontario. The unique facility, located 2 km underground, offers abundant shielding against cosmic rays. The SuperCDMS experiment...

As part of the Dark Matter search by SuperCDMS at SNOLAB, HVeV detectors are used to provide a mechanism of detecting eV-scale energies. HVeV detectors are typically made of high-purity silicon operating with a high bias voltage at sub-K temperatures. An excitation to the silicon generates electron/hole pairs that drift due to the bias voltage. The phonons produced by the drift are expected to...

In the Fall of 2019, the NEWS-G experiment used its latest detector, a 140 cm diameter Spherical Proportional Counter (SPC) to search for low-mass dark matter at the Laboratoire souterrain de Modane (LSM), in France. Having the sphere filled with pure methane, hydrogen was used as the target to produce new limits on the spin-dependent cross-section around masses of 1 GeV.

In this talk I will present preliminary results regarding the application of machine learning techniques for noise removal on signals from spherical proportional counters (SPCs) with the NEWS-G experiment. In SPC detectors, a primary ionization, created by a particle interacting with the gas, drifts towards a central anode. When ions approach the anode, the electric field becomes strong enough...

The TUCAN collaboration aims to make a measurement of the neutron electric dipole moment (nEDM) with a precision of 10-27 e cm, an order of magnitude improvement over the current best limit. A non-zero nEDM would be explicit evidence for CP violation in the Standard Model. This, in turn, contributes to solving the longstanding baryon asymmetry problem. Such a measurement requires an...

The TUCAN EDM experiment at TRIUMF will use polarized, ultracold neutrons (UCNs) to search for the neutron electric dipole moment (nEDM). The discovery of a permanent nEDM would indicate the violation of time reversal symmetry, and thus charge-parity symmetry (given the CPT theorem). This would point to physics beyond the Standard Model of Particle Physics. To achieve the projected sensitivity...

The Multi-Ion Reflection Apparatus for Collinear Laser Spectroscopy (MIRACLS) is a novel approach in performing high-resolution collinear laser spectroscopy (CLS) in a multi-reflection time-of-flight (MR-ToF) device. By trapping a 30-keV ion beam in-between the MR-ToF’s electrostatic mirrors and revolving it around a few thousand times through an optical detection region (ODR), significant...

As the heaviest known fundamental particle, the top quark plays a special role in many theories of new physics beyond the Standard Model. Reconstruction of top anti-top pair production to the best possible resolution is therefore crucial to enhancing our sensitivity to Beyond Standard Model effects in precision measurements and searches at the Large Hadron Collider (LHC), from improved mass...
