Improvements to Asay Foils for Enhanced Dynamic Range and Robustness*

Recent changes to Asay foil designs and manufacturing processes have improved robustness against shock, vibration and laser heating during fielding operations. Experimental data shows Asay foils survive more than 40x expected shock and vibration environments and more than 10x expected laser heating energies. Moreover, a fielding strategy is presented and experimentally verified with explosively-driven Sn ejecta that yields 5x improved dynamic range in cumulative ejecta areal mass measurements.
