Numerical analysis of thermodynamical process in the thin metal samples irradiated by IPIB

In this paper, we simulate, based on our one-dimensional coupled fluidplastic model, the thermodynamicalprocesses in the thinmetalsamples that are irradiated by intense pulsed ion beam (IPIB) with different pulse parameters. The pulse parameters are: ion energy from 300 to 1000 keV, current density from 10 to and pulse duration from 10 to 80 ns. With the calculation result, distributions of the sample densities and temperatures are discussed. Furthermore the shocks generated by IPIB are paid more attention in our discussion, including their generation, propagation, reflection at the back and surface of the sample, and its possible influence on the sample properties as well.
