| Abstract Scope |
Until the production of a FPNS or operational fusion research reactor, the study of materials degradation under the fusion environment must be done with surrogate irradiations. Temperature, dose rate, time, and transmutation will all be hugely influential in the evolution of materials for fusion, and at present can only be partially accounted for with existing irradiation methods. It is therefore necessary to understand the specific limitations in the application of surrogate irradiations to simulate the fusion environment.
This work presents a characteristic view of high temperature Ni+ and He+ ion irradiations and compares the morphology of characteristic defects to that of the Ni+ only and He+ only exposed conditions. This is done to help elucidate the effects of each ion implantation as well as the synergistic effects which arise from their combined application, revealing fundamental insight into the applications of ion irradiations in the simulation of the fusion environment. |
