Dual-beam irradiation facility for Energy science and Technology (DuET) has been used to support nuclear industry researches as well as those of non-nuclear field. Both the in-situ and post-irradiation experimental techniques, which are critical to understand radiation damage mechanisms such as irradiation creep, irradiation hardening evaluation by nano-indentation method and fabrication procedure of TEM thin foiles, are introduced. Besides radiation induced lattice defect formation, an example of surface modification technology using ion-accelerators is also introduced.
