Detector development and testing
Science & Capabilities
Neutrons are a precious and irreplaceable scientific resource. They follow the quantum mechanical spin of the electrons in solids, penetrate sample chambers to look at materials under extreme conditions, and provide unique information about the building blocks of life. Through ongoing consultation with ORNL staff, users, expert advisory committees, and workshop participants from the broader research community, science priority areas have been identified with research challenges and opportunities that can be best addressed by the unique and vital information provided by neutron scattering.
