Continuous and scalable polymer capsule processing for inertial fusion energy target shell fabrication using droplet microfluidics

Abstract High specification, polymer capsules, to produce inertial fusion energy targets, were continuously fabricated using surfactant-free, inertial centralisation, and ultrafast polymerisation, in a scalable flow reactor. Laser-driven, inertial confinement fusion depends upon the interaction of h...
