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.

Hydrodynamics growth experiments involve rippled ablator samples (CHx, Ge:CH, or Si:CH). The rippled surface features a microscale mathematical shape (sinusoidal functions are widely used). Nevertheless, experiments have progressed with time, and samples evolved gradually from two-dimensional (planar samples) to three-dimensional geometries (capsules).
This paper presents various processes that have been developed to fulfill such specifications. Various technologies, based on laser means (excimer laser, Ti:sapphire laser) or mechanical ultraprecision means, have been successfully applied to ripples machining (planar samples or capsules).
The main results are discussed showing the ability and accuracy of each technology as well as their main limitations. We focus especially on our latest results (i.e., rippled or grooved capsules).
