AB  - A mathematical model of the SVZ-100 lead slowing-down neutron spectrometer designed at the Institute for Nuclear Research, Russian Academy of Sciences (Moscow) is presented. The neutron spectra in the SVZ-100 measuring channels are calculated by the Monte Carlo method at different slowing-down times. The influence of the energy resolution of the spectrometer on the shape of the neutron cross sections is demonstrated. The developed model makes it possible to establish agreement between experimental data obtained using neutron spectrometers by different methods and with different resolutions and compare the results of measuring the neutron cross sections of thorium and transuranic elements using the SVZ-100 with recommended international databases.

AB  - Lead slowing-down (LSD) spectrometers have a low energy resolution (about 30%), but their luminosity is 10(3) to 10(4) times higher than that of time-of-flight (TOF) spectrometers. A high luminosity of LSD spectrometers makes it possible to use them to measure neutron cross section for samples of mass about several micrograms. These features specify a niche for the application of LSD spectrometers in measuring neutron cross sections for elements hardly available in macroscopic amounts-in particular, for actinides. A mathematical simulation of the parameters of SVZ-100 LSD spectrometer of the Institute for Nuclear Research (INR, Moscow) is performed in the present study on the basis of the MCNPX code. It is found that the moderation constant, which is the main parameter of LSD spectrometers, is highly sensitive to the size and shape of detecting volumes in calculations and, hence, to the real size of experimental channels of the LSD spectrometer.
