A086200100004 AUTHOR (M.Zamani, S.Stoulos, M.Fragopoulou, M.Manolopoulou, A086200100005 M.Krivopustov) A086200100006 REFERENCE (J,ANE,37,923,2010) A086200100007 INSTITUTE (4ZZZDUB) A086200100008 (2GRCARU) Aristotle University of Thessaloniki, A086200100009 School of Physics, Greece A086200100010 FACILITY (ACCEL,4ZZZDUB) Accelerator of the High Energy A086200100011 Laboratory, JINR,Dubna,Russia. A086200100012 GAMMA-2 transmutation Set-up. A086200100013 METHOD (ACTIV) A086200100014 (EXTB) A086200100015 INC-SOURCE (SPALL) The inelastic cross section of relativistic A086200100016 protons in Pb was determined indirectly by measuring A086200100017 the neutron distribution along a Lead spallation A086200100018 neutron source. A086200100019 The spallation neutron source was irradiated by 1, 1.5 A086200100020 and 2 GeV protons. The experimental results were A086200100021 obtained using passive methods. By the use of the beam A086200100022 attenuation coefficient, deduced by a fitting procedureA086200100023 of experimental data, the inelastic cross section of A086200100024 protons in Pb was determined. A086200100025 SAMPLE A cylindrical Pb target, with 40 cm length and 8 cm in A086200100026 diameter covered with a paraffin moderator 6 cm in A086200100027 thickness. A086200100028 DETECTOR (TRD) The neutron distribution was studied on the A086200100029 paraffin moderator a long the target by using Solid A086200100030 State Nuclear Track Detectors(SSNTDs). A086200100031 Natural Cd foils (mass approx.2 gram, purity 99.9%, A086200100032 thickness 1 mm) were also used as an activation A086200100033 detector. A086200100034 COMMENT *By author*.Each part of the neutron spectrum was A086200100035 measured by using two different techniques. A086200100036 Neutron fluencies are presented for three neutron A086200100037 energy ranges. Thermal neutrons with En < 1 eV, slow A086200100038 (1 eV < En < 10 keV) and fast neutrons A086200100039 (0.3 MeV < En < 3 MeV) are shown for an irradiation ofA086200100040 the target with protons of 1 GeV. Slow neutrons were A086200100041 measured by Cd-nat activation method while thermal A086200100042 neutrons with En < 1 eV and fast neutrons by SSNTDs A086200100043 technique.
