Flyer acceleration by high-power laser and impact experiments at velocities higher than 10 km/s

Impact velocity of meteorites on planetary and satellite surfaces at the final stage of planetary accretion becomes more than 10 km/s. Recently, we have developed a macroscopic (larger than 0.1 mm) flyer acceleration technique to velocities more than 10 km/s using high-power lasers. In this presentation, we show that higher impact velocities than 10 km/s can be achieved using sheet flyers with a diameter of 0.6 mm and a thickness of 0.03 - 0.05 mm and spherical projectiles with a diameter of 0.1 - 0.3 mm, and that various impact experiments are carried out using this technique.
