Abstract

Abstract

Organic polymer foams have many uses in inertial confinement fusion targets and Z-pinch loads. However, many low density foams are not uniform in some extent, which has bad effects on their performance. Two techniques, the beta radiation technology and X-ray computed tomography(CT) are used for density uniformity characterizing. The data show that the trimethylolpropane trimethacrylate(TMPTA) polymer foams have small density variations: the density is greater at the outer edges than that of the interior of foam. The experiment shows that the measurement of the density distribution in foams can meet the requirement of experiment fundamentally at present, while the spatial resolution and the density resolution need improvement.
