Target thickness and laser intensity dependence of ion implosion in hollow cylindrical targets
The applications of energetic ions are valuable in various fields such as medical and fusion research. Recently, micro-bubble implosion, a scheme used to generate energetic ions at high densities, has been proposed. This study used simulations to investigate the ion density evolution of a hollow cylindrical hydrogen target undergoing micro-bubble implosion. We also examined how the target thickness and laser intensity affect the implosion time. Our simulations show that ion implosion occurs for varying target thicknesses and laser intensities. Furthermore, increasing the target thickness resulted in a faster implosion time. Increasing the laser intensity also resulted in a more rapid ion implosion.
