Abstract

A two-dimensional code to simulate the operation of laser-driven in-tube accelerator has been developed. The code includes laser ray-tracing and ionization non-equilibrium for an analysis of realistic operation. The feature of the blast wave can be reproduced with this code and the process of the generation of the laser-induced blast wave is analyzed. Moreover, our computational results show that the generated shock waves are repeatedly reflected on the tube wall and the projectile base. The quantitative comparisons with the experimental data are also presented.
