TL;DR: In this paper, the authors explored novel concepts for fusion chamber technology that can substantially improve the attractiveness of fusion energy systems, including the potential for: (1) high power density capability; (2) higher plasma β and stable physics regimes if liquid metals are used; (3) increased disruption survivability; (4) reduced volume of radioactive waste; (5) reduced radiation damage in structural materials; and (6) higher availability.

TL;DR: In this article, the authors focus on the gap between near-term and long-term concepts for high heat flux components (HHFC), and in particular for divertors, with the aim of characterizing the international status of current HHFC design concepts.

TL;DR: In this article, the effect of edge power loading on the shape of the ITER divertor was investigated, and it was concluded that the geometrical approximation for leading edge power load on radially misaligned poloidal leading edges is indeed valid.

TL;DR: A review of the potential of robust PFCs with liquid surfaces for applications in future D/T fusion device summarizes the critical issues for liquid surfaces and research being done worldwide in confinement facilities, and supporting R&D in plasma surface interactions as mentioned in this paper.

TL;DR: The Advanced Divertor and RF tokamak eXperiment (ADX) as discussed by the authors is designed to address critical gaps in the world fusion research programme on the pathway to next-step devices: fusion nuclear science facility (FNSF), fusion pilot plant (FPP) and/or demonstration power plant (DEMO).
