Application of Nuclear Physics Methods for Identification of Complex Chemical Substances

Leader:

M.G. Sapozhnikov

Scientific Programme:
The main goal is to develop methods for identification of complex chemical substances by registration of the gamma-quanta spectra induced by fast neutrons irradiation. The neutrons are produced in the reaction d+t

+n. The

-quanta are registered in coincidence with

particles. For each event the coordinates and the arrival time of

particles in the alpha-detector are measured as well as amplitudes and arrival time of

in the gamma-detectors. This information allows to find the 3D position of the object inside the interrogated volume. Investigations of different detectors for

and

registration will be performed. The data acquisition and data analysis systems will be manufactured. Simulation of the neutrons and gamma-quanta interactions in the interrogated volume will be done to optimize the detector. The prototypes of the detector to identify hidden substances will be constructed.

Expected main results in 2006:

Investigation of different types of alpha-detector.
Construction of the system of gamma-detectors.
Experiments at Van de Graaf accelerator to test searching algorithms.
Construction of the working prototypes of the system with portable neutron generator.
Monte Carlo simulation of the identification algorythms.
