Nuclear fusion research is one of the very interesting subject of applied physics not only from the side of plasma physics but also from the component developments and related problems under fusion reactor environment such as vacuum wall, superconductive coil, surface phenomena, bulk radiation damage, etc. These problems must be defined through conceptual designs of fusion reactor of four generation, namely, physical and engineering feasibility, reactor with energy pay back and compatibility with environment.
The constructions of large fusion devices are also one of the subject of applied physics, which correspond tothe method of experimental physics to assemble device and to do reasonable experiment.
