    Owing to its depth underground, SNOLAB is an excellent site for hosting rare event searches such as searches for WIMP-like dark matter or neutrinoless double beta decay. The overburden of rock at SNOLAB provides a reduction in the cosmic muon flux of over 7 orders of magnitude as compared to the flux at sea level. Still, even the residual fluxes of cosmic muons can contribute to backgrounds;...

    Single photon detectors are used in a wide range of experiments at SNOLAB, from SNO, to DEAP-3600, and experiments on the horizon, nEXO and ARGO. The technology continues to evolve from vacuum Photo-multiplier tube to Silicon photo-multiplers, to the future "photon to bit" converter. I will review the evolution of the technology and highlights its relevance to ongoing and future experiments at...

    To address the risks Canadians face from radon, Health Canada leads the National Radon Program. Under this program, targeted research aims to close knowledge gaps and, in conjunction with outreach and stakeholder engagement, informs Canadians of these health risks and motivates action to reduce them. Integral to the program, Health Canada regularly reviews and updates the national radon risk...

    SNO+, the successor experiment to the Sudbury Neutrino Observatory (SNO), is now filled with an optimized scintillator mixture after an initial water fill and a sustained period of being partially filled with scintillator. The SNO+ experiment has demonstrated good neutron detection through all phases of the experiment to date, allowing for the detection of anti-neutrinos by the inverse beta...

    Control of the SNO+ detector has evolved since commissioning was completed and shifting started in 2017. SNO+ used control rooms with a minimum of 2 computers to perform monitoring and control of the detector. Through the years of successful data taking by hundreds of shifters, the obvious question is, can this task be done by fewer people? Freeing up students, postdocs and faculty to do other...

    Similar to semiconductor electronics, ionizing radiation upsets superconducting electronics. However the research on mitigating the impact of ionizing radiation on superconducting electronics is not well developed. We describe an experiment to operate an array of superconducting qubits underground at the CUTE facility in SNOLAB.

    Radon is a limiting background in many leading dark matter and low energy neutrino experiments. One way to mitigate radon background is to fill external experimental components with a clean cover gas such as N2. At SNOLAB, the radon concentration in the experiments cover gas system are monitored using a radon assay board. To improve the sensitivity of gas assays a new trapping mechanism is...

    The establishment of advanced nuclear detection technology is critical for enhancing security and monitoring capabilities of nuclear materials. At CNL, we are focused on implementing transition-edge sensor (TES) technology to achieve superior detection performance over traditional techniques such as high-purity germanium detectors. TES sensors are renowned for their high resolution and...

    In the study of reactor and geo antineutrinos, tagging of the inverse beta decay (IBD) positron-neutron coincidence signature allows for the elimination of most backgrounds. In many detectors, the primary remaining background is caused by captures on 13C — so called (⍺, n) events — which release a neutron and closely mimic the IBD's signature. The most common (⍺, n) prompt event is produced by...

    The accurate modelling of underground muon fluxes is critical for the success of underground experiments in particle astrophysics, providing essential background understanding for rare event searches such as neutrinoless double beta decay and dark matter interactions.

    Natural background ionizing radiation is ubiquitous, yet its biological significance remains elusive.

    The nEXO experiment is a proposed next-generation liquid xenon detector to search for neutrino-less double beta decay (0νββ) of $^{136}$Xe. The experiment will use a 5-tonne liquid xenon monolithic single-phase time projection chamber enriched to 90% in $^{136}$Xe. Ionization electrons and scintillation photons from energy deposits in the Xe will be recorded by a segmented anode place and a...

    Radon is an unwanted background in current rare-event search experiments taking place at SNOLAB. The radon is ever-present and naturally occurring due to the uranium and thorium in the surrounding rock in the mine, and as such poses challenges when creating a system for radon mitigation. SNO+ is a multi-purpose neutrino detector and radon is one of the backgrounds that needs to be well...

    We discuss some small-scale searches for rare events that may benefit from the low-radioactivity environment of SNOLAB. The mechanisms include standard nuclear decays which will inform nuclear models and matrix elements, and which are of interest to other fields such as neutrinoless double beta decay. A related example is revisiting the decays of uranium of importance in geochronology. ...

    SNO+ is a liquid scintillator-based neutrino detector that aims to detect neutrino-less double beta decay (NDBD) which can confirm whether the neutrino is its own antiparticle or not. The detection process demands a very low radiogenic background level, good energy resolution, and at the same time large mass of isotopes in the detector. 130Te is chosen due to its high isotopic abundances for...

Cryogenic distillation is a proposed alternative that depends on the relative...
