The neutron transport in the lead slowing down spectrometer LSDS-100 was
simulated by Monte Carlo method. The dependence of the response function and of its central
moments on the slowing down time were investigated. The neutron density shape versus on time
was calculated as well as the time spectra of the fission events for some targets (235U, 239Pu). The
simulated characteristics of LSDS are compared with the experimental ones.
