2D rad-MHD model assessment of designs for multiple-shell gas nozzles for Z

Jones, Brent M.; Coverdale, Christine A.; Ampleford, David A.; Jennings, Christopher A.; Cuneo, M.E.

AASC is designing multiple-shell gas puff loads for Z. Here we assess the influence of the loads initial gas distribution on its K-shell yield performance. Emphasis is placed on designing an optimal central jet initial gas distribution, since it is believed to have a controlling effect on pinch stability, pinch conditions, and radiation physics. We are looking at distributions that optimize total Ar K-shell emission and high energy (>10 KeV) continuum radiation. This investigation is performed with the Mach2 MHD code with non-LTE kinetics and ray trace based radiation transport.
