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 differential cross sections for the production of gamma radiation from fast-neutron inelastic scattering have been measured at incident neutron energies from 4.00 to 7.67 MeV for Be, C, O, Al, Si, Fe, Ni, Nb, W, and 239Pu. The gamma-ray spectra were measured with a NaI(Tl) spectrometer using time-of-flight techniques to eliminate the neutron background. The gamma-ray detector was surrounded with a large NaI(Tl) annulus operated in the anticoincidence mode. The resulting spectra were unfolded and appropriate corrections were applied for neutron and gamma-ray attenuation, for electronic dead time, and for detector efficiency.
