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.

High resolution measurements have been made of the gamma-ray spectrum produced in liquid nitrogen by a 14-MeV neutron source. The spectra of gamma rays from neutron inelastic scattering were measured to a distance of six feet by pulsing the source. Comparison of the inelastic photon flux with discrete ordinates calculations using ENDF/B neutron cross sections and recent gamma-ray production cross sections shows good agreement for the strong well-resolved lines. The results of unfolding the continuum part of the spectrum reveal a flux of high energy lines that is a sizable fraction of the total flux of resolved lines. These normally unresolved gamma rays account for part of the gap in the nitrogen nonelastic cross section.
