MOBILE DEVICE FOR IDENTIFYING CONCEALED SUBSTANCES (VERSIONS) Russian patent published in 2012 - IPC G01N23/222 

FIELD: physics.

SUBSTANCE: sealed housing of an inspection module is made from electrically insulating material and also has not less than three γ-ray detectors, wherein all detectors lie sideways from a neutron generator in form of a matrix having common protection from the stream of labelled monochromatic neutrons; line laser generators are mounted on the housing of the inspection module from the outside with possibility of removal and installation thereof and with possibility of indicating on the inspected object boundaries of exposure thereof to the stream of labelled monochromatic neutrons; the spectroscopic channel of the γ-ray detector is fitted with a thermo-correction system consisting of a thermal detector mounted on the chip of the γ-ray detector in thermal contact with it, an amplitude-to-digital converter (ADC) and a single-board computer. The thermal detector is connected by a communication line and a power line to the amplitude-to-digital converter, which is connected by a system bus to the single-board computer which is connected to the power supply system of the device and a control module.

EFFECT: achieving maximum possible intensity of the detected characteristic gamma-radiation, high time resolution of the system, high sensitivity of the gamma-detector, reduced number of errors associated with lack of compensation for change in ambient temperature, high accuracy of guiding and controlling the exposure area of the analysed object, as well as further reduction in the minimum detected mass of the concealed dangerous substance.
