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 neutron fission cross section of 241Am was measured in the energy range from 10 to 1030 keV using 235U as a standard. The measurements were carried out at the Karlsruhe 3-MV pulsed Van de Graaff accelerator with 7Li targets for the generation of a continuous neutron spectrum below 140 keV and monoenergetic neutron spectra between 120 and 1030 keV. Fission events were detected by measuring the prompt fission neutrons with an NE-213 liquid scintillator with pulse-shape discrimination. The flight path was as short as 60 mm in measurements with continuous neutron spectra leading to a moderate energy resolution. The statistical uncertainty was between 0.8 and 10% and the systematic uncertainty between 5.4 and 8.5%. Discrepancies were found when comparing our results with those of other experiments.
