LRT 2019, hosted by the Laboratorio Subterráneo de Canfranc (LSC), Spain.

The Low Radioactivity Techniques (LRT) workshop series examines topics in low radioactivity materials and techniques, a fundamental aspect of rare event searches.

Topics include global radioactivity measurement and screening facilities, low background counting techniques, purification and contamination control, Rn control, cosmogenic activation of materials, and backgrounds and simulations for rare event experiments related to dark matter, solar neutrinos, double-beta decay and long half-life phenomena. This conference’s wide scope includes all aspects of the development of low background detectors and techniques.

The goal of this workshop series is to bring together experts in this field for presentations and discussion covering broadly the issues of 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.

This edition of the workshop will be hosted by the Laboratorio Subterráneo de Canfranc (LSC), which is the second largest deep underground scientific laboratory in Europe. The LSC is located at the heart of the Spanish Pyrenees, the second most important mountain range in Europe and one of the most beautiful and impressive natural reserves of the continent. Sessions will be run in the nearby town of Jaca, very core of the Pyrenean region and its most important city. It is one of the most dynamic and lively towns of northern Spain, with a strong image and a national point of reference for winter sports and nature tourism.

This is the seventh workshop in the LRT series. Previous LRT workshops have been held around the world:

• LRT2017 hosted by the Institute for Basic Science (IBS) Center for Underground Physics (CUP) and by Ewha Womans University.
• LRT2015 hosted jointly by PNNL and the University of Washington in Seattle, USA
• LRT2013 at LNGS in Assergi, Italy
• LRT2010 at SNOLAB in Sudbury, Canada
• LRT2006 hosted by LSM in Aussois, France
• LRT2004 inaugural meeting, hosted at Laurentian University in Sudbury, Canada.
