Abstract A-FNS and IFMIF-DONES neutron source program in Japan and in the EU, respectively, are advancing targeting on the start of operation in ∼2030. These facilities will play a central function in realizing DEMO. This paper will discuss the role of the materials scientists, as the users, in A-FNS and IFMIF-DONES programs in order to encourage them to enhance their commitment to the programs. The past collaborations by the materials scientists and the designers in the IFMIF project are introduced first. Then the roles of the neutron sources in the DEMO-roadmap are discussed, for which materials scientists are requested to take leadership. This paper also emphasizes the need for development of advanced materials and for obtaining fundamental understanding on fusion neutron radiation effects by application of the neutron sources.
