The basis of this method is the selection of the spectral distribution of the conversion electrons from a mixed range of the electron beam. This division is obtained using a two-channel detection module, containing two planar silicon detector thickness of 300 microns with gadolinium converter and without. When designing a system for detection of thermal neutrons used dual-detector module based on the planar silicon detectors developed in KIPT, as well as various sources of ionizing radiation and control instrumentation. As a result of the work in stages 1 and 2 is designed two-detector detection system based on uncooled silicon detectors and metal gadolinium for detection of thermal neutrons with the ability to tune out background radiation, including: simulated radiation processes, diffusion and absorption of particles in two-detector module in the capture of thermal neutrons by means of a software package GEANT4; made to develop a model and testing the physical processes occurring during the passage of the spectrum of thermal neutrons in dual-detector modular system; developed software complex "Si_converter", which takes into account the actual geometry dual-detector module to track the transportation of neutron fluxes, in-line to view the transfer and absorption of the secondary radiation, to simulate the processing and comparison of each channel dual-detector system; calculated the passage of neutrons, electrons and CXR, depending on the geometrical dimensions of the components of the module dual-detector system; simulated response in the implementation of the method of gamma-electron separation of mixed signal (dual-detector system) by the action of the mixed flow to the real geometry and arrangement of the components of the module; designed according dual-detector module design based on uncooled silicon detectors with converters of metal gadolinium; designed electric signal processing circuit from the two-detector unit; developed software to measure the spectra of thermal neutron; made two-detector module for the detection of thermal neutrons based on uncooled silicon detectors with a converter of a metal gadolinium; studied two-detector module based on uncooled silicon detectors and metal gadolinium for detection of thermal neutrons; studies have shown that the application module based on dual-detector uncooled silicon detectors and gadolinium metal registration allows the possibility of thermal neutrons with detuning from background radiation. Subsequent operation is advantageously carried out in research towards developing a multifunctional device for measuring both the gamma radiation and thermal neutrons.
