Milestone 7720: National Opacity Program - Tri-Lab Assessment of Measurements and Models

Hansen, Stephanie B.; Heeter, Robert; Johns, Heather; Nagayama, Taisuke; Loisel, Guillaume P.; Bailey, James E.

Opacity-on-NIF has obtained opacity data under conditions similar to those achieved by the entirely different Opacity-on-Z platform. From low- and high-Z elements at different anchor points, rigorously compare the opacity data between the laboratories and to multiple opacity theory models. Compare and assess the data acquisition and processing methods for obtaining opacities and for measuring/inferring sample conditions. Explain, or develop hypotheses for, any discrepancies. Map progress to the National Opacity Strategy and define future directions.
