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 sensitivity of the accuracy of the forward space and adjoint space calculation of a detector response in a source driven system to the order of the angular quadrature used is investigated. It is found that for problems characterized by a localized source and extended detector distributions, the adjoint space calculation may require a significantly lower order of angular quadrature than the forward space calculation. The reciprocal situation prevails for problems characterized by an extended source and localized detector distributions.
