We report on the results of the 10th Non-LTE code comparison workshop, which was held at
the University of San Diego campus November 28 through December 1, 2017. Non-
equilibrium collisional-radiative models predict the electronic state populations and
attendant emission and absorption characteristics of hot, dense matter and are used to help
design and diagnose high-energy-density experiments. At this workshop, fifteen codes from
eleven institutions contributed results for steady-state and time-dependent neon, aluminum …
