Topics in Astroparticle and Underground Physics 2019/09/09 SNOLAB Update Jeter Hall Director of Research
The SNOLAB Facility • Hosted at the Vale Creighton Nickel Mine in Sudbury, Ontario, Canada • Operated as a joint venture of 5 Canadian Universities: Carleton, Queen’s, Montreal, Alberta, and Laurentian • Operations funded by the Canada Foundation for Innovation and the Province of Ontario • ~100 staff and >850 users from 128 institutions in 22 countries. 2
Science at SNOLAB The science at SNOLAB is currently focused on fundamental particle physics. Primarily looking at further investigating the nature of matter . Specifically: • What is the nature of dark matter? • What is the nature of the neutrino? SNOLAB is interested in collaborating on any scientific research that benefits from deep underground facilities. For example: • Neutrino observatories (solar, supernovae, etc.) • Effects of radiation on biological systems • Environmental monitoring (nuclear non-proliferation, aquifers, 4D Earth, etc.) 3

Excellent progress from the current suite of experiments SNO+ is analyzing and publishing DEAP is analyzing and publishing CUTE has seen ionizing radiation PICO-40 has seen ionizing radiation DAMIC is analyzing and publishing HALO is analyzing, publishing, and ready REPAIR is growing 5
data from SNOLAB @ TAUP C. Krauss talk from DM1 for PICO-40 update • T. Noble talk from DM10 for PICO future program • S. Westerdale and M. Boulay talks for DEAP-3600 analysis and results • • Also see many talks from other global argon efforts T. Aramaki in DM7 for SuperCDMS updates and status • A. Chavarria in DM7 for DAMIC status • • P. Privitera in DM7 and D. Baxter in DM4 for DAMIC-M update G. Gerbier in DM7 for NEWS-G updates • * This list is likely not complete. Apologies to those I didn’t call out. 6

We are researching and developing shielding and low background construction The researchers that includes world leading expertise in low background materials. Real-time assay of radioactive fallout during construction. 8
We are researching and developing radon abatement and assay 9
An injection of 65M$ in Canada to support astroparticle physics Strengthen international collaborations. “ To be a globally recognized centre for research and learning, coalescing Canadian and international expertise in underground particle astrophysics and benefitting from the unique SNOLAB facility to deliver world-leading science focused on the big questions in particle astrophysics, cosmology and astronomy.” Numerous programs have been launched: - 15 new faculty members - About 85 research staff. Postdocs, students - Support for research – experiments and R&D - International programs include: - Support for visiting scientists/sabbaticals to or from Canada - A PhD exchange program. To give students the opportunity to gain experience at another institution in or outside Canada. (So far exchanges with Japan, Portugal, UK….) 10 https://mcdonaldinstitute.ca/

LEGEND 1000 concept From talk by W. Pettus Next generation neutrino and dark matter experiments nEXO concept from talk by M. Heffner • Watching the Canadian community planning` process • Tonne-scale neutrinoless double-beta decay (DOE Nuclear Physics CD0) • Generation-3 Dark Matter (DOE High Energy Physics P5) • Dark Matter New Initiatives (DOE High Energy Physics Program) 12 From ‘Building for Discovery’ P5 report (2014)
Laboratory Space • Strawman plan for laboratory expansion now exists • Cost for expansion is ~120M CAD • Not actively proposing to expand • Expect space allocations may be more competitive in the future 13
SNOLAB includes a campus 2 km underground 14
