A new Multiple Beams–Material Interaction Research Facility for radiation damage studies in fusion materials

As an important part of fusion materials research, evaluation of radiation damage in fusion materials has been emphasized more than two decades. Under the current situation with no 14 MeV neutron irradiation facility available for materials research, Multiple Beams–Materials Interaction Research Facility has to have a very important role in many years to come. In order to obtain clear understandings of radiation damage in fusion materials, as the dynamic material behavior under severe environments in advanced energy systems, such as fusion reactors, fission reactors, a Multiple Beams–Material Interaction Research Facility (DuET facility) has been constructed at the Institute of Advanced Energy, Kyoto University, in these three years. And is at the first stage of accelerator operation and adjusting. The facility consists of a 1.7 MV tandem accelerator system with a pair of ion sources (a cesium sputter type heavy ion source and a duo-plasmatron type light ion source), a 1.0 MV single-end accelerator system with a light ion source and three target stations. Some of the preliminary results utilizing HIT Facility, the University of Tokyo, is also provided with the future plan.
