The ablation mass of metals by intense pulsed ion beam irradiation

摘要

Ablation effect plays an important role in the process of material modification by intense pulsed ion beam (IPIB). As a direct observable in the process of target irradiated by IPIB, the ablation mass is a crucial physical quantity for understanding the interaction between IPIB and target material. Moreover, it is critical to uncover the mechanism of ablation by IPIB. In the present work, we used IPIB provided by BIPPAB-450 accelerator at Beihang University to bombard Zn, Pb, Sn, Cu, and W targets. By measuring the ablation masses under different energy densities, the ablation thresholds of Zn and Pb have been obtained. In addition, correlations between experimental data and incident beam parameters have been investigated. The results are helpful to understand the influence of beam parameter and material properties on the ablation mass.
