The Status of Studies on Structural Materials under High Energy Proton and Neutron Mixed Spectrum Y. Dai and W. Wagner Paul Scherrer Institut, Villigen PSI, Switzerland Corresponding Author: yong.dai@psi.ch The R&D of spallation targets with either high power or high proton beam intensity has been stimulated by increasing demands for different applications such as neutron scattering science and nuclear waste transmutation devices. One of key issues in the R&D is the understanding of the behaviors of structural materials in severe irradiation environments in spallation targets. A world-wide effort has been focused on studying the radiationdamage effects of high energy protons and spallation neutrons on different structural materials by conducting irradiation experiments in the targets of the Swiss spallation source (SINQ) at the Paul Scherrer Institut. In the last few years, a large number of specimens irradiated in the SINQ targets were examined in several institutions in Europe, Japan and USA. A significant progress has been achieved in the basic understanding of the radiation effects and alarge amountdatahavebeen obtainedfrom the related post-irradiation examinations. In this report, thepresent status and main outcome of these studies will be described.
