摘要
用基于两体碰撞近似的计算机模拟程序MARLOWE研究能量为10keV-50keV的聚变α粒子在材料中产生的能量沉积、移位和替位碰撞以及损伤深度分布。并与蒙特卡洛模拟的结果进行了比较。与解析理论一致,辐照产生的空穴数与材料中的弹性能量沉积成正比,两者有相似的分布。文中还讨论了不同靶材料中辐照损伤的差别。
The energy deposition, production of displacement and replacement collisions induced by fusion α-particles with energies from 10keV to 50keV are studied by computer code MARLOWE based upon binary-collision approximation. The results are compared with the Monte-Carlo simulation. The number of vacancies is found to be proportional to the elastic energy, deposition, in agreement with analytical theory. The similar profiles are observed for both elastic energy deposition and vacancies. The radiation damages caused by α-particles in different target elements are discussed as well.
