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 external bremsstrahlung (EB) spectra generated in thick targets by the beta particles of 170Tm are measured using a 4.55- × 5.08-cm NaI(Tl) crystal detector in a good geometry setup. The raw spectra are unfolded using the Liden-Starfelt procedure. The unfolded EB spectra are compared with Bethe-Heitler, Elwert-corrected Bethe-Heitler, Morgan-corrected Bethe-Heitler, and Tseng and Pratt theories. The experimental spectra are found to agree with the theory of Tseng and Pratt up to a certain energy and deviate positively thereafter. The deviation from theory increases with increasing energy and atomic number of the target material.
