To understand and reliably predict the irradiation performance of materials, it is important to understand the fundamental effects of radiation on materials at the atomic scale. At the most basic level, radiation effects are caused by the creation of point defects including interstitial defects, substitutional defects and vacancies. Point defects are created when an incident particle or a...
Diamond is expected to be applied to next-generation power electronics and quantum sensor, due to its excellent and unique physical properties. As in the field of semiconductor device industry with other materials, ion implantation technology is indispensable for realizing diamond devices because of its design flexibility, where depth and concentration can be controlled by ion energy and...
FLUKA [1-3], developed and maintained by the FLUKA.CERN Collaboration, is a general-purpose code for the Monte Carlo (MC) simulation of radiation transport. It is capable of accurately accounting for the transport and interaction of over 60 particle species (photons, leptons, hadrons, and ions) in complex material geometries on a broad energy range, from the keV (meV for neutrons) up to the...
Material damage index of displacement per atom (dpa) is calculated by the particle flux and the displacement cross section. Since the experimental data of the displacement cross section was scarce, the measurements using protons were conducted, and so far, the experimental data of protons up to 30 GeV have been obtained in J-PARC and other Japanese facilities. The displacement cross section...
