LRT 2022, Co-hosted by South Dakota Mines and the Sanford Underground Research Facility (SURF)

The Low Radioactivity Techniques (LRT) workshop series examines topics in low-radioactivity materials and techniques that are fundamental for quantum information science and rare-event searches, including dark matter, solar neutrinos, double-beta decay, long half-life phenomena and nuclear astrophysics.

The workshop features updates from underground laboratories around the globe as well as the latest information regarding all aspects of low background detectors, techniques and assay programs in addition to recent developments in advanced machining and 3D printing using ultra-pure materials.

The goal of this workshop series is to bring together experts in this field for presentations and discussion broadly covering topics related to low radioactivity techniques. The intention is to foster and continue the collaboration and resource sharing required for new generations of detectors to be developed at underground facilities.

The workshop is being hosted in the Black Hills of South Dakota at SD Mines in Rapid City, near SURF which is the deepest underground laboratory in the United States. The area’s natural beauty attracts tourists year-round, and has strong connections to Native American culture and history.

Initiated by the Sudbury Neutrino Observatory in 2004, the 2022 meeting is the 8th international topical workshop in the LRT series:

• LRT2019 hosted by the Laboratorio Subterráneo de Canfranc (LSC) in Jaca, Spain
• LRT2017 hosted jointly by the Institute for Basic Science (IBS) Center for Underground Physics (CUP) and Ewha Womans University in Seoul, South Korea
• LRT2015 hosted jointly by PNNL and the University of Washington in Seattle, USA
• LRT2013 hosted by Laboratori Nazionali del Gran Sasso (LNGS) in Assergi, Italy
• LRT2010 hosted by SNOLAB in Sudbury, Canada
• LRT2006 hosted by Laboratoire Souterrain de Modane (LSM) in Aussois, France
• LRT2004 hosted by SNO at Laurentian University in Sudbury, Canada

The workshop will follow the APS Code of Conduct.
