Giant Radio Array for Neutrino Detection

GRAND is a next-generation detector designed to collect ultra-high energy cosmic particles as cosmic rays, neutrinos and photons, in order to solve the long-standing mystery of their origin. It will consist in an array of 200,000 radio antennas deployed over 200,000 square kilometers, about the size of Great Britain, in favorable mountainous locations in the world. It will be the largest ground detector ever built.

The GRAND Green Policy was approved!

The Green Policy discussed at the 2021 Collaboration meeting was voted and approved by the core-team meeting on January 21, 2022. It outlines a set of guidelines which the GRAND Collaboration promotes and commits to follow to the best of its capabilities.

The GRAND Carbon footprint study is out!

Large-scale physics and astrophysics experiments gather a large fraction of the scientific staff and absorb a significant volume of the science budget. As such, it seems essential to assess their environmental impact. Researchers Clarisse Aujoux, Kumiko Kotera and Odile Blanchard led a pioneering study on the Carbon footprint of the GRAND Project.
