Query: NUCLEON-2 Mission for the investigation of heavy cosmic rays nuclei   The NUCLEON-2 experiment is aimed at the investigation of isotope and charge
composition of ions from carbon up to trans-uranium elements in the energy
range over about a hundred MeV/N. The concept design of the NUCLEON-2 satellite
cosmic ray experiment is presented. The performed simulation and preliminary
prototype beam test confirms the isotope resolution algorithms and techniques.
