Title PINS Variance Study.
Publication Date Aug 2013
Media Count 27p
Personal Author E. H. Seabury
Abstract The INL's Portable Isotopic Neutron Spectroscopy System (PINS) non-intrusively identifies the chemical fill of munitions and sealed containers. PINS is used routinely by the U.S. Army, the Defense Threat Reduction Agency, and foreign military units to determine the contents of munitions and other containers suspected to contain explosives, smoke-generating chemicals, and chemical warfare agents such as mustard and nerve gas. The objects assayed with PINS range from softball-sized M139 chemical bomblets to 200 gallon DOT 500X ton containers. INL had previously examined the feasibility of using a similar system for the identification of explosives, and based on this proof-of-principle test, the development of a dedicated system for the identification of explosives in the presence of special nuclear material for emergency responders was started in 2011. INL tested prototype PINS on explosives and mock explosives with kilogram quantities of highly-enriched uranium and weapons-grade plutonium in 2011. In 2012 INL concentrated on making the system more sensitive to identifying explosives, particularly in the detection of the nitrogen content of explosives. This past year INL has been concentrating its efforts in studying the variance in the spectra, in particular the variance in the elemental ratios that are used to identify individual explosives.
