摘要

摘要: 文章为研究低能质子与S781白漆的微观交互作用，利用SRIM-2003软件模拟了10～150 keV质子辐照S781白漆过程，计算了S781白漆及其ZnO颜料、粘结剂组分的核阻止本领、电子阻止本领、电离损失、位移损失以及质子的射程。结果表明，S781白漆的电子阻止本领远大于核阻止本领，辐照损伤以电离效应为主，电离损失主要发生在ZnO颜料上。

Abstract: The interaction between low-energy protons (10 ~ 150 keV) and S781 white paint is simulated by using SRIM-2003 software. The stopping power of nucleus and electron, the energy loss related with ionization and displacements, and the range of the protons in S781white paint and in its two components of ZnO pigment and the binder are included in the simulations. The results indicate that the stopping power of electron is far greater than that of nucleus, and the radaition damage in S781 white paint is mainly due to ionization. Furthermore, our simulations also show that the ionization-related energy loss is mostly caused by ZnO pigment.
