Abstract

Low density foam shells with high optical transmittance for fuel targets for the coming upgrade laser systems were developed by increasing the polymerization initiator for trimethylolpropane trimethacrylate in an oil phase of a water/oil/water emulsion. Foam with similar performance was fabricated using reduction-oxidation polymerization of ethyleneglycol dimethacrylate. These results showed that a cryogenic fuel layer sustained by these foam layers can be charecterized using optical interference technique.
