| Research Abstract |
The recent progress in the laser-driven ion acceleration field make us possible to achieve compact ion accelerator system. The laser-driven ion have peculiar characteristics, such as, ultra-small acceleration field, high peak current, and low transverse emittance. At the same time the beam shows large divergence angle and broad energy spread, resulting the low density ion beam away from the source position. In this research we try to apply the additional acceleration and focusing fields towards the ions emitted from the source. The additional field originates from the combination between the recycling of the "escape electrons from the target" and the special design target holder.
