Irradiation system based on dodecahedron for inertial confinement fusion

Two different types of irradiation systems based on dodecahedral configuration are proposed for 60, 72, 80, and 92 beams. By optimizing the system, it is expected that enough uniformity (≤1% rms) is provided. Furthermore, it is quantitatively discussed that the number of beams, power imbalance, and the beam pattern must be improved synchronously for a high illumination uniformity.
