Abstract
Spherical hollow polymer foam shells used as a sustainer of cryogenic fuel for the inertial fusion target have been developed. Foam shells which have 500–1000 μm diameter with a 30–100 μm uniform wall, 4 μm cell size and 40 mg/cm3 density, have been fabricated using a dual‐nozzle droplet generator and a freeze‐dry technique. Requirements to obtain a uniform thick wall and fine cell size are discussed.Keywords
