Abstract

An emulsion encapsulation method is applied to the fabrication of polymer capsules in inertial confinement fusion (ICF) experiments. Craters on the capsule surfaces make the capsules useless. This paper introduces the origins of the craters and focuses on ways to remove the craters from polymer capsules. Three origins are discussed and their influence can be restrained to reduce the cratering to meet the demand for mass production of targets.
