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.

A miniature NE-213 scintillation counter and hydrogen proportional counters have been used in conjunction with a calibrated 14-MeV deuterium-tritium neutron source to measure the neutron flux per source neutron per second at a number of positions in a 1.25-m-diam sphere of lithium fluoride. The experimental techniques used are discussed, and the resulting neutron spectra are compared with those from one-dimensional Sn calculations using the ENDF/B-IV data set, allowance being made both for neutron yield anisotropy and for the variation in source neutron energy with angle of emission.
