Transmutation studies with GAMMA-2 setup using relativistic proton beams of the JINR Nuclotron
A spallation neutron source consisting of of lead target and paraffin moderator were irradiated by 1.0, 1.5, and 2.0 protons. Reaction rates of various transmutation reactions were studied, especially for minor actinides, fission pr...

Tailored instrumentation for long-pulse neutron spallation sources
Long-pulse spallation sources will offer a very high time-integrated neutron flux similar to that of the best steady-state sources. Using Monte Carlo simulations we show that the exceptional source qualities transl...

Measurements of Cross-sections of the Neutron Threshold Reactions and Their Usage in High Energy Neutron Measurements at "Energy plus Transmutation"
Cross-sections of (n,xn) threshold reactions in Au, Al, Ta, In, Bi, and I were measured up to 97 MeV. Two different quasi-monoenergetic sources were used. In the paper is furthermore demonstrated the application of gained results for the
