TL;DR: In this article, the authors review the underlying physical processes and the existing experimental database of plasma-material interactions both in tokamaks and laboratory simulation facilities for conditions of direct relevance to next-step fusion reactors.

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: The status of the research on muon colliders is discussed and plans are outlined for future theoretical and experimental studies in this paper, where various components in such colliders, starting from the proton accelerator needed to generate pions from a heavy-$Z$ target, proceeding through the phase rotation and decay, muon cooling, acceleration, storage in a collider ring, and the collider detector.

TL;DR: In this paper, the authors investigated spatio-temporal evolution of ns laser ablation plumes at atmospheric pressure, a favored condition for laser-induced breakdown spectroscopy and laser-ablation inductively coupled plasma mass-spectrometry.

TL;DR: In this paper, the status of the effort to realize a first neutrino factory and the progress made in understanding the problems associated with the collection and cooling of muons towards that end are described.
