Registration of the thermal neutrons using uncooled Si planar detector
The registration of thermal neutrons by Si planar detector with natural metallic Gd neutron converter was performed. The ²³⁹Pu-Be(α, n) fast neutron source with flux 1.13·10⁵ с⁻¹ with paraffin moderator for obtaining of thermal neutrons was used. Control measurements of the thermal neutron flux...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | The registration of thermal neutrons by Si planar detector with natural metallic Gd neutron converter was
performed. The ²³⁹Pu-Be(α, n) fast neutron source with flux 1.13·10⁵ с⁻¹ with paraffin moderator for obtaining of
thermal neutrons was used. Control measurements of the thermal neutron flux by detector-dosimeter MKS-01R were
performed. Experimental spectra for the reaction Gd(n, γ)Gd were measured. Spectra consisted of the spectra
conversion electrons in energy range 30…200 keV with maximum at energy ~ 70 keV and Gd CXR lines.
Background gamma-radiation was measured by Si PIN detector without Gd plate. Program code GEANT4 for the
calculation of the thermal neutron flux was used. |
