The CTBT: Science and Technology 2017 Conference (SnT2017) takes place from 26 to 30 June 2017 at the Hofburg Palace in Vienna, Austria. It is the sixth in a series of multidisciplinary conferences designed to further enhance the strong relationship between the scientific and technological community and the CTBTO.

The conference series provides a forum for scientists from around the world to exchange knowledge and share advances in monitoring and verification technologies of relevance to the Comprehensive Nuclear-Test-Ban Treaty (CTBT). Such interaction helps ensure that the Treaty’s global verification regime remains at the forefront of scientific and technical innovation.

With around 1,000 participants from over 120 countries, 650 abstracts, nearly 400 posters, and over 100 oral presentations, this is the largest Conference to date.

A comprehensive record of materials from past conferences in this series is available under Conference Series Science and Technology Series.
