METHOD FOR DETECTION, INDENTIFICATION AND LOCALIZATION OF ORGANIC SUBSTANCES, INCLUDING EXPLOSIVE AND NARCOTIC SUBSTNACES, WITH USE OF IMPULSE FLOW OF FAST NEUTRONS Russian patent published in 2004 - IPC

FIELD: technology for analyzing substances with radiation methods.

SUBSTANCE: method includes radiation of object by non-collimated flows of fast neutrons, and for localization of organic substance data concerning registration times of characterizing gamma-quanta receiving in several, no less than three, positions of device relatively to radiated object is used. Radiation of object with impulse flows of fast neutrons is stopped in case of absence of increase of radiation level by flow of registered characterizing gamma-quanta during time, necessary for detection of organic substances. Also, for receiving impulse flows of fast neutrons single-atom deuterium ions are used from ion source, ions are accelerated in pre-accelerator, sent to high frequency scanning device with collimator, in which impulse beams of deuterium ions are formed, beams are directed to grouper for grouping ions on speed basis, impulse beams of ions are accelerated in electrostatic accelerator and tritium target is bombed by ions.

EFFECT: lesser time needed for controlling object, lesser costs of device.
