METHODS AND SYSTEMS FOR TEMPERATURE CONTROL OF FUSION TARGETS

摘要

A hohlraum for an inertial confinement fusion power plant includes a generally cylindrical body having a laser entrance hole opening in opposite ends thereof to enable laser beams to reach an interior surface of the generally cylindrical body. The hohlraum also includes a first window covering the laser entrance hole in a first end of the generally cylindrical body and a first raised protrusion surrounding the first window. The first raised protrusion creates a first region of ambient gas stagnation adjacent the first window when the hohlraum is moving, to thereby reduce heat flow into the hohlraum.
