SRIM（以前的TRIM）蒙特卡罗模拟代码被广泛用于计算与材料的离子束注入和离子束处理相关的许多参数。它也有能力计算一个共同的辐射损伤曝光单位，称为原子位移每原子（dpa）。由于dpa是初级辐射损伤产生的标准度量，因此大多数使用离子束作为诱导材料辐射损伤的工具的研究人员使用SRIM来确定与其辐照相关的dpa。使用SRIM为此目的进行了评估和比较已与国际公认的标准定义的dpa，以及更详细的原子模拟原子位移级联。标准和SRIM为基础的DPA之间的差异进行了讨论，并为今后使用SRIM在辐射损伤研究的建议。特别是，建议在打算直接比较离子和中子数据时，应选择SRIM的Kinchin-Pease选项。(C)2013爱思唯尔有限公司版权所有。
The SRIM (formerly TRIM) Monte Carlo simulation code is widely used to compute a number of parameters relevant to ion beam implantation and ion beam processing of materials. It also has the capability to compute a common radiation damage exposure unit known as atomic displacements per atom (dpa). Since dpa is a standard measure of primary radiation damage production, most researchers who employ ion beams as a tool for inducing radiation damage in materials use SRIM to determine the dpa associated with their irradiations. The use of SRIM for this purpose has been evaluated and comparisons have been made with an internationally-recognized standard definition of dpa, as well as more detailed atomistic simulations of atomic displacement cascades. Differences between the standard and SRIM-based dpa are discussed and recommendations for future usage of SRIM in radiation damage studies are made. In particular, it is recommended that when direct comparisons between ion and neutron data are intended, the Kinchin-Pease option of SRIM should be selected. (C) 2013 Elsevier B.V.
