pulsed fast neutron analysis

pulsed fast neutron analysis

[¦pəlst ‚fast ′nü‚trän ə‚nal·əsəs] (engineering) A technique for detecting contraband materials, in which a pulsed beam of high-energy neutrons is scanned up and down in a raster pattern while the object under inspection is conveyed through the beam; characteristic gamma rays emitted by materials in the object are detected in order to analyze and image these materials with the help of time-of-flight measurements.
