Title: PKA spectrum and radiation damage for 150-MeV electrons on Type 316 stainless steel

Abstract

Consideration has been given to using 150-MeV electrons at the Oak Ridge Electron Linear Accelerator in an attempt to simulate the radiation damage effects of 1-GeV protons at the Spallation Neutron Source (SNS) on Type 316 stainless steel (316SS). The purpose of this study is to calculate the primary knocked-on atom (PKA) spectrum and the displacement cross sections for 150-MeV electrons on 316SS, and to compare them with earlier corresponding determinations for 1-GeV protons. It seems quite clear that 150-MeV electron irradiations do not provide a good approximation to the displacement damage characteristics of 1-GeV proton irradiations on 316SS. The PKA spectrum for the electron irradiations is much more weighted toward low-energy transfers to the target atoms, and a considerably lower displacement cross section is achieved.
