| Abstract: | 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. |
