2001 - Timed Neutron Detector

Developer: Richard Craig

The Timed Neutron Detector (TND) was honored by Discover Magazine with the 2001 Christopher Columbus Fellowship Foundation Award. This award is given to a living American currently working on a discovery that will significantly affect society and that needs additional funds to be realized. The TND, developed by Dick Craig and Tony Peurrung, looks similar to a metal detector, yet it applies neutron physics to find indications of a land mine's presence. The system detects hydrogen, which is present in casings and explosives found in plastic or metal land mines, and hydrogen's interactions with neutrons. Thus land mines can be accurately and safely located for disarming.
