Analogy between laser shock and HVI coupled with flyer plate impacts development

HyperVelocity Impacts (HVI) are encountered in various natural context such as meteorite impacts, planetary accretion and water transport within the solar system and in space applications. The development of the analogy between HVI and laser shock opens new perspectives. Indeed, the laser versatility coupled with in-situ diagnostics enables reproducing and studying well-identified natural impacts in laboratory. The analogy consists in the direct comparison between target’s craters due to either laser shock or equivalent sphere impact. Here we propose to test it at ESRF-HPLF but also to extend to flyer plate impacts. Indeed, flyer plates can also directly be accelerated, for a large velocity range, using high-energy lasers. Our study will open new perspectives at HPLF with a new driving scheme to produce laser-driven plate impacts instead of direct laser ablation, resulting in higher shock loading uniformity and offering the possibility to perform absolute Hugoniot measurements.
