DESCRIPTION:Speakers: Alexey Afonin (INR RAS)\nA W-Be-photoneutron neutron
  source IN-LUE based on a linear electron accelerator was created and inst
 alled at the Institute for Nuclear Research of RAS [1]. The shape of the n
 eutron spectrum and flux estimation was obtained earlier as a result of si
 mulation [2]. Due to the impossibility of measuring the neutron spectrum i
 n a wide range of energies within the source\, various methods of spectrum
  unfolding based on the solution of the inverse problem are usually used.\
 nIn this work\, the results of unfolding the neutron spectrum into photone
 utron source chamber of the source are presented. As experimental data for
  unfolding\, we used the data of neutron activation analysis of samples ir
 radiated in the source (Ag\, Mg\, Mn\,Sb\, Ti\, etc.). To unfold the spect
 rum\, a number of well-known Nuclear Energy Agency (NEA) programs were use
 d [3]\, which implement various algorithms for solving the inverse problem
 . \nThis work also presents the results of measurements of the neutron flu
 x by various methods\, as well as their comparison.\n \n1. A.V.Andreev et
