Abstract

Confined plasma ablation is an efficient method to accelerate 1-D metal plates, with the impact of the plate resulting in a well-defined shock being generated in a target material. By using confined plasma to accelerate a plate, some details of the laser parameters are decoupled from the plate impact. Several types of experiments and related diagnostics to evaluate the performance parameters of the laser beam, flyer plate acceleration, and plate conditions are described. Several experiments using the flyer plates to generate shocks in materials to determine pressure-velocity relations, and dynamic spall strength of various metals are presented.
