摘要: 利用Monte-Carlo方法模拟了电子在材料中的输运过程,得到了材料中电子的能量沉积剖面,同时结合弹塑性流体力学方程组,对"闪光二号"脉冲电子束发生装置产生的电子束与Ly-12铝相互作用的热-力学效应逐炮进行了数值计算,着重研究了喷射冲量及质量亏损,并与实验测试结果进行了对比。

Abstract: Using Monte-Carlo method, the electon transport and energy deposition in material are calculated. Combining with the elastic plastic hydrodynamic equations, numerical results cover the thermal mechanical effect and the blowoff impulse on Ly-12 Al induced by irradiating of the impulsive electrobeam which caused by ‘FLASH Ⅱ’-an impulsator of relativistic electron beams. these results are compared with the experimental data.

Key words: impulsive electro-beam, numerical calculation, blowoff impulse, Monte-Carlo method
