Project summary

The basic purpose of the project is creation on the basis of the high-frequency linear hydrogen ions accelerator of the complex intended for use as an intellectual means of explosive (ES) and fissionable substances (FS) detection and control in inspected objects, which can be applied at the airports for the customs control.

The essence of the project consists in realization of explosive and fissionable substances detection method on the basis of use of a pulse neutron source based on linear high-frequency high-current small-sized hydrogen ions accelerator in a combination with matrix detection system of gamma and neutron radiation registered at the moments of accelerator current pulses and in the intervals between them.

Detection of the secondary radiation are made by the matrix of scintillation detectors operating in integrated, spectrometric and temporal modes of synchronous detector method, allowing to receive reliable results in conditions of small statistics that raises probability of detection of required elements at their low concentration. Use of high-frequency linear accelerators allows to induce high flows of pulse neutron radiation (up to 1015n/sec per pulse) at insignificant mass and scale characteristics of the complex even with the use of local radiation shield.

Within the framework of works, explosive and fissionable substances detection testing technique, development and manufacturing of highly effective matrix of scintillation detectors with control and experimental data processing system are assumed to be provided with ISTC financing.

Now in NPK LUTS there is an experimental sample of the small-sized high-current hydrogen ions accelerator with output energy 2 MeV, which can be successfully used as a pulse source of neutron radiation.

The realization of the project will allow to involve in the given work scientists, earlier actively working above the defensive order.
