Taking shape: Fusion energy ecosystems built with public-private partnerships
It’s possible to describe fusion in simple terms: heat and squeeze small atoms to get abundant clean energy. But there’s nothing simple about getting fusion ready for the grid.
Private developers, national lab and university researchers, suppliers, and end users working toward that goal are developing a range of complex technologies to reach fusion temperatures and pressures, confounded by science and technology gaps linked to plasma behavior; materials, diagnostics, and electronics for extreme environments; fuel cycle sustainability; and economics.

We investigate the ability of light extinction spectrometry (LES) to characterize, at long distances, the size distribution and concentration of dust mobilized by laser cleaning methods (ITER wall detritiation and characterization of deposition layers) or by experiments dealing with a loss-of-vacuum accident. Potentially harmful effects induced by wall proximity, plasma plume broadband emission, and associated shock waves are shown to have a negligible influence on LES measurements, which demonstrates the interest in this optical technique for the aforementioned studies. However, our experimental results, based on aerosols of silica and tungsten powder aggregates, show that the present setup allows the characterization of dust volume fractions of less than [approximately equal]1-10 ppb for a probing length of 1 m (or by extrapolation [approximately equal]0.1-1 ppb for a probing length of 10 m).
