Neutron spectrum analyses of spallation neutrons are conducted in the accelerator-driven system (ADS) facility at Kyoto University Critical Assembly (KUCA). High-energy protons (100 MeV) obtained from fixed field alternating gradient accelerator injected onto a tungsten target, whereby generated. For neutronic characteristics neutrons, reaction rates and continuous energy distribution measured by foil activation method an organic liquid scintillator, respectively. Numerical calculations executed MCNPX with JENDL/HE-2007 ENDF/B-VI libraries to evaluate foils (bismuth indium) set target front target. method, C/E values between experiments found around relative difference 10%, except for some reactions. observed up 45 MeV. From these results, neutron information on generated attained successfully injecting 100 MeV
