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.

In this investigation, variance measurements of the secondary electron emission current from an evacuated chamber have been performed and a formula to calculate in these experiments has been derived. The value obtained for is within 50% of obtained with a gas detector and a factor of 2 greater than calculated values. The mean track length and the Vtrack term were also calculated for this irradiation geometry, Vtrack being of the same order of magnitude as Vtrack for a sphere.
