Characterization Of Lithium-6 As A Commercial Helium-3 Alternative For Nuclear Safeguards And Security, Alexander Martin Okowita
Characterization Of Lithium-6 As A Commercial Helium-3 Alternative For Nuclear Safeguards And Security, Alexander Martin Okowita
Masters Theses
Helium-3 detectors are efficient, reliable neutron detectors, but their high demand has reduced their supply to a very miniscule level, making them very expensive. The goal of this project is to test and evaluate an alternative produced by industry. Current testing is being done with a Lithium Zinc Sulfide (6LiF:ZnS(Ag)) detector from Aspect used in their portal monitors.
There are three basic requirements for neutron detectors used in nuclear safeguards and security: 1) high absolute detection efficiency, 2) maintaining neutron detection efficiency when simultaneously exposed to a high gamma ray exposure rate, and 3) the ability to maintain …
