First demonstration of improving laser propagation inside the spherical hohlraums by using the cylindrical laser entrance hole
The octahedral spherical hohlraums have natural superiority in maintaining high radiation symmetry during the entire capsule implosion process in indirect drive inertial confinement fusion. While, in contrast to the cylindrical hohlraums, the narrow space between the la...

| description | The octahedral spherical hohlraums have natural superiority in maintaining high radiation
symmetry during the entire capsule implosion process in indirect drive inertial
confinement fusion. While, in contrast to the cylindrical hohlraums, the narrow space
between the laser beams and the spherical hohlraum wall is usually commented. In this
Letter, we address this crucial issue and report our experimental work conducted on the
SGIII-prototype laser facility which unambiguously demonstrates that a simple design of
cylindrical laser entrance hole (LEH) can dramatically improve the laser propagation
inside the spherical hohlraums. In addition, the laser beam deflection in the hohlraum is
observed for the first time in the experiments. Our 2-dimensional simulation results also
verify qualitatively the advantages of the spherical hohlraums with cylindrical LEHs. Our
results imply the prospect of adopting the cylindrical LEHs in future spherical ignition
hohlraum design. |
