| Abstract Scope |
Ion irradiation has been widely used as a surrogate for reactor neutron irradiation. One issue and artifact from ion irradiation is the so-called injected interstitial effect, in which the implantation introduces extra interstitials that locally suppress void swelling. A method based on the self-consistency of swelling data as a function of local dpa has been recently developed to identify the affected region. So far, however, there are no studies on the safe zone of proton irradiation. Proton irradiation is largely different from heavy ion irradiation, not only because of its very different defect morphology but also due to the absence of injected self-interstitials. Implanted hydrogen will influence defect clustering through its chemical effect and bonding with defects. In this talk, the safe analysis zone of both self-ion irradiation and proton irradiation is reported and compared. The study is important for the credibility of ion irradiations. |
