The Cryogenic Underground TEst facility (CUTE) – developed as a test facility for devices that require low temperatures (~10 mK) and low backgrounds – is operational at SNOLAB since 2019. Particular care was also taken in providing a low-noise and low-vibration environment for the experimental setup. This presentation discusses the features and performance of the facility, the current...

The possible need of nearly 50 tonnes of 136Xe to search for neutrinoless double beta decay motivates an investigation of economical ways to enrich the xenon. The technique currently available at a limited number of manufacturers is centrifuge separation. Distillation is a potential alternative that relies on the isotopic variation of vapour pressures. Our group has provided the first credible...

Astroparticle physics experiments searching for rare events, such as neutrinoless double beta decay and dark matter particle interactions, have to be shielded from background radiation and have to exhibit a radioactive background as low as reasonably achievable. The material selection for the next generation of low-background experiments is becoming crucial to inform the final design of the...

As the inexorable march of particle and astrophysics continues, the requirements for purity of metals for use in every conceivable aspect of these experiments grows. Returning to one of the very first metals utilized in large scale by humans, we are embarking upon a New Copper Age in particle and astrophysics, requiring previously near inconceivable levels of elemental purity and perfection...

Backgrounds from radon decay products are problematic for current and future low energy neutrino and rare-event searches. At SNOLAB we have various instruments in order to monitor radon in the air and in ultra pure water and to constrain radon emanating from detector components. We also have brand new data acquisition system used for radon counting. My talk will focus on these topics and...

Multiple projects as SNOLAB use liquid nitrogen to cool and operate their experiments on a day-to-day basis. High purity Nitrogen is also used for cover gas, purification processes, and operating high purity equipment. Currently, up to 3,000 L per week of Liquid Nitrogen is shipped underground at SNOLAB and consumed.
This project will generate high purity liquid nitrogen (99.999%)...
