GRACE

Man-portable system that identifies chemicals in munitions and sealed containers

Man-portable system that identifies the chemical contents of munitions and other unopened containers without opening or sampling them. It uses PINS technology: a neutron generator excites the nuclei in the object and the emitted gamma rays are measured by a mechanically cooled HPGe spectrometer. The system is carried in two carbon-fibre backpacks and controlled from a rugged tablet.
