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.

Thomson scattering (TS) is the most reliable diagnostic to measure the electron temperature and electron density radial profiles. In GAMMA 10, the yttrium-aluminium-garnet (YAG)-TS system was constructed with the large solid angle of TS collection optics. We carried out the Rayleigh and Raman scattering experiments for system settings and applied the YAG-TS system to the GAMMA 10 plasma. We can successfully measure the electron temperature and density radial profiles in the central cell of GAMMA 10 by using YAG-TS system. The supersonic molecular beam injection (SMBI) experiments have been started for plasma fueling study in GAMMA 10. In SMBI experiments, we observed the electron temperature decrease and electron density increase in the plasma center.
