Schematic of flyer impact experiments.
Detail of coatings between substrate and flyer.
Example temporal history of laser pulse. The pulse shape was reproducible.
Example of acceleration and displacement history (shot 14 119: Cu flyer, 10 J drive).
Velocity history for Cu flyers.
Line VISAR record for shot 14 119. Fringes are displaced spatially as the flyer accelerates: the displacement is proportional to the speed. The field of view was 4 mm, centered on the center of the flyer. The flyer diameter was 5 mm.
Variation of flyer kinetic energy with specific laser energy measured against flyer mass.
Acceleration history, predicted with heat source applied uniformly over working fluid.
Pressure history in working fluid, predicted with heat source applied uniformly over working fluid.
Temperature history in working fluid, predicted with heat source applied uniformly over working fluid. (Central group from bottom to top: , 10 J; , 11 J; , 11 J.)
Idealized velocity history for flyer acceleration and impact, based on flyer.
Comparison between ideal velocity history and typical record (shot 14 140). The deviation between the records following the first reverberation after impact was caused by optical damage to the window.
Flyer Hugoniot points compared with Hugoniot from published equation of state. The Marsh points lying well below the curve are for porous samples.
