| 摘 要： | Two-dimensional numerical research has been carried out on the ablation effects of
titanium target irradiated by intense pulsed ion beam (IPIB) generated by TEMP II
accelerator. Temporal and spatial evolution of the ablation process of the target
during a pulse time has been simulated. We have come to the conclusion that the
melting and evaporating process begin from the surface and the target is ablated
layer by layer when the target is irradiated by the IPIB. Meanwhile, we also
obtained the result that the average ablation velocity in target central region is
about 10\,m/s, which is far less than the ejection velocity of the plume plasma
formed by irradiation. Different effects have been compared to the different ratio
of the ions and different energy density of IPIB while the target is irradiated by
pulsed beams.
