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 semiempirical formula for the gamma-ray albedo of alternating layers is proposed. The values of the albedo calculated by this formula agree with the experimental ones for alternating layers of tin-aluminum and lead-aluminum slabs within ∼10%, except for the case of very thin alternating layers. This formula was applied to the angular distribution of photons backscattered by the alternating layers and the difference between experimental and calculated values was < 18%.
