Uncertainty Characterization of Silicon Damage Metrics
Here, a general formulation of silicon damage metrics and associated energy-dependent response functions relevant to the radiation effects community is provided. Using this formulation, a rigorous quantitative treatment of the energy-dependent uncertainty contributors is performed. This resulted in the generation of a covariance matrix for the displacement kerma, the NRT-based damage energy, and the 1-MeV(Si) equivalent damage function. Lastly, when a careful methodology is used to apply a reference 1-MeV damage value, the systematic uncertainty in the fast fission region is seen to be removed and the uncertainty for integral metrics in broad-based fission-based neutron fields is demonstrated to be significantly reduced.
