Abstract and subjects
We have performed shock compression experiments at the Los Alamos Neutron Science Center (LANSCE) at the proton radiography (pRad) facility on a porous, low-Z material: APO-BMI. APO-BMI is a carbon micro-balloon filled foam that has homogenous pore sizes that measure 20-50 µm. The motivation for these experiments was to advance our understanding of uncertainties inherent in the shock compression of porous materials. We were able to concurrently collect dynamic radiography images with the traditional velocimetry data to directly compare these diagnostics and to, perhaps, better understand experimental uncertainties inherent to shock compression of these low-Z, porous foams.
