Abstract

The Karlsruhe Light Ion Facility (“KALIF”) is a pulse power accelerator delivering up to ~40 kj proton beam energy at power densities on target up to 1 TW/cm2. For the 10– to 20 μm-thick energy deposition layer in a solid target, simulations predict temperatures of several tens of eV, pressures in the 10– to 100 GPa-range and densities which rapidly decay due to material ablation. Applying a laser Doppler velocimeter, we have utilized the dynamic response of 20– to 50 μm-thick planar metal targets to investigate the ion beam properties and to measure the ablation pressure. Thin metal foils were accelerated to velocities beyond 12 km/s. To demonstrate the potential of KALIF as a fast ablative shock-wave generator we have performed dynamic tensile strength measurements in the nanoseconds load duration regime.
