A Y-12 nuclear nonproliferation technology offering significant possibilities in the homeland security field was among those listed on the R&D Magazine 51st Annual R&D 100 Awards. The honor salutes the 100 most technologically significant products introduced into the marketplace during the past year.
The LISeTM, a high-efficiency thermal neutron detector based on the 6LiInSe2 crystal, is the first large, single-crystal semiconductor of high resistivity that contains lithium and directly detects thermal neutrons with high efficiency. The single-crystalline device will be used in handheld nuclear nonproliferation and homeland security applications to find fissile materials. Its simpler, more compact design, and higher efficiency are key improvements that will appeal to users. [Read more…]
