中文摘要：

基于超短激光驱动的质子源的照相技术是传统质子照相技术的发展.使用FLUKA蒙特卡罗（MC）程序,依据激光质子源的特点,对质子照相进行了定量的模拟研究.通过对三种典型情况的模拟（半平面靶及台阶靶,激光惯性约束聚变研究用黑腔,磁场网格照相）分析了影响质子照相的主要物理因素,表明了激光质子照相具有对界面敏感,高空间分辨,对磁场敏感的优点.

英文摘要：

Radiography using ultra-short laser-produced proton beams is a development of traditional proton radiography. According to the characteristic of laser-produced proton beam,using FLUKA Monte-Carlo program,the quantitative simulation of proton radiography is studied. From the simulation of three typical cases （half-plane target and ladder target,hohlraum with a plastic ball in it,and detection of magnetic field with mesh method）,the main physical factors that effect the proton radiography are discussed. The advantage of radiography of laser-produced protons,such as high sensitivity to boundary,high spatial resolution,and high sensitivity to magnetic field,is demonstrated.
