Abstract
Ablation effects play an important role in material processing with intense pulsed ion beam (IPIB) and IPIB diagnostics such as calorimeters and infrared detection may also be influenced by ablation. In this study, with numerical analysis and thermal imaging method, the ablation plume and its effects on energy deposition of IPIB on solid target was studied. Radiation experiments of polyvinyl chloride (PVC) targets with a thickness of 200 μm were carried out on BIPPAB-450 pulsed ion beam accelerator and the energy deposition of the ion beam was investigated with infrared imaging diagnostics. It is revealed that due to the low thermal conductivity and decomposition temperature of PVC, ablation plume can be formed during the early stage of beam irradiation and the ablation product may shield the energy of the ion beam from depositing in the target when energy density reaches a certain threshold. This effect needs to be taken into consideration in order to avoid its influence on applications and beam diagnostics.
