利用拟合实验测得的TEMPⅡ型加速器磁绝缘二极管电压波形及其焦点附近束流密度曲线,建立了Gauss分布模型.采用Monte Carlo方法研究了强流脉冲离子束与铝材镀有不同厚度金膜的双层靶(金膜与铝材合称为双层靶)之间的相互作用,模拟了能量沉积的演化过程和随不同金膜厚度的变化情况.对脉冲离子束强化薄膜粘结性进行了探讨.
Gaussian distribution models of voltage wave form of magnetically insulated diode(MID) of TEMPⅡ accelerator and intense pulsed ion beam(IPIB) density near the MID focus region have been built according to the results of experiments.Interaction of IPIB with a double-layer aluminum target coated by a thin film of gold has been studied using Monte Carlo method.The spatial and temporal evolution of deposited energy is obtained,the states of deposited energy for the different gold thickness are discussed,and the enhanced adhesion at interfaces by IPIB is investigated.
