ABSTRACT

To develop advanced nuclear materials, lots of irradiation experiments have been done to various materials in different conditions. Accurate quantification of the defects induced by irradiation is important for researches in nuclear materials, especially when evaluating the damage caused by different particles. An advanced model – athermal recombination corrected dpa (arc-dpa) is recently introduced. In order to apply arc-dpa on experimental data, overall arc-dpa in ion and neutron irradiated iron, copper and tungsten are calculated based on the arc-dpa function for single cascade and the calculated PKA energy spectra. Data of irradiation experiments are re-evaluated with our applicable arc-dpa. The use of arc-dpa on experimental data showed good fit, giving new insights into the evolution of irradiation damage done by different particles.

使用计算出的适用 arc-dpa 重新评估离子和中子辐照数据

摘要

为了开发先进的核材料,已经对各种材料在不同条件下进行了大量辐照实验。准确量化辐射引起的缺陷对于核材料的研究非常重要,尤其是在评估不同粒子造成的损害时。最近推出了一种高级模型 - 无热复合校正 dpa (arc-dpa)。为了将arc-dpa 应用于实验数据,基于单级联的arc-dpa 函数和计算的PKA 能谱计算离子和中子辐照的铁、铜和钨中的总体arc-dpa。使用我们适用的 arc-dpa 重新评估辐照实验的数据。arc-dpa 对实验数据的使用显示出良好的拟合,为不同粒子造成的辐射损伤的演变提供了新的见解。
