Neutron reaction cross sections of 241Am have an important impact on transmutation blanket neutronics design and nuclear explosion diagnosis. The reliability of the data has to be validated by integral experiments; however, the neutronics experimental data on 241Am is still lacking at present. In this work, the transmutation blanket mockup would be established based on accerellator-based fusion neutron source and depleted uranium blocks. The experimental data of 241Amfission rate and capture reaction rate distribution would be obtained through investigating the key techniques in measurement of fission rate, capture rate of 241Am , low energy neutron measurement and so on. Transmutation characteristics and law would be investigated by combining the measurement of differential cross section; the neutron distribution and transportation law would be studied from neutron spectrum above the resonance region. Finally, the integral test and analysis on neutron data of 241Am would be conducted. The results of this study can provide benchmark experimental data and technique support for the accuracy and reliability of the transmutation blanket physical design.
