In transition: Commercializing fusion power
Commercial fusion power is closer than ever. There are now around 30 U.S. fusion companies, several of which claim to be on track to connect to the grid as early as the 2030s.
Tokamak and laser inertial confinement approaches benefit from decades of research at facilities such as the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory and ITER, with alternative concepts including stellarator, magnetic mirror, and Z-pinch confinement also making notable progress as private and government funding for fusion increases.

The transmitted photon spectra of133Ba, 137Cs, and 60Co sources are measured through different thicknesses of a soil medium. A multiple-scatter peak is observed at an energy of 100 keV independent of incident photon energy and thickness of the medium. The intensity of the peak decreases exponentially with the increase in thickness of the medium. A linear relationship between the effective atomic number of the medium and the multiple-scatter peak energy is observed.
