TL;DR: In this article, a novel octahedral spherical hohlraum with cylindrical LEHs and LEH shields was proposed to increase the laser coupling efficiency and improve the capsule symmetry and mitigate the influence of the wall blowoff on laser transport.

TL;DR: The first spherical hohlraum energetics experiment is accomplished on the SGIII-prototype laser facility and it is indicated that the radiation temperatures measured by the FXRDs depend on the observation angles and are related to the view field.

TL;DR: The role of hohlraum geometry in LPI is demonstrated and the need for systematic experiments for choosing the optimal configuration for ignition studies with indirect drive inertial confinement fusion is demonstrated.

TL;DR: A new laser-driven spherically convergent plasma fusion scheme (SCPF) that can produce thermonuclear neutrons stably and efficiently is investigated and theoretically predict the neutron yield Y_{n} to be related to the laser energy E_{L}, the hohlraum radius R_{h}, and the pulse duration τ through a scaling law of Y_{ n}∝(E_{L}/R_{h}^{1.2}τ^{0.2}.

TL;DR: In this paper, a comparison between spherical and cylindrical hohlraums was performed at the SGIII laser facility, where three kinds of filling are considered: vacuum, gas-filling with or without a capsule inside, and a flat-top laser pulse with 3 ns duration and up to 92.73 kJ energy.
