Measuring the Effect of Heterogeneous Mix on Thermonuclear Burn in the Marble Campaign Using an Argon/Tritium Fill Gas

The Marble\footnote{T J Murphy {\it et al,} J Phys:Conf Series {\bf 717}, 012072 (2016).} campaign on NIF quantifies the effect of heterogeneous mix on thermonuclear burn for comparison to a probability distribution function (PDF) burn model.\footnote{J R Fincke, unpublished; J R Ristorcelli, Phys Fluids 29, 020705 (2017).} MARBLE utilizes plastic capsules filled with deuterated plastic foam and tritium-containing gas. Recent experiments, which utilized an argon-tritium gas mixture, show the expected decrease in DT/DD yield ratio with non-uniform initial foam morphology, while previous experiments with a hydrogen-tritium gas mixture did not.\footnote{T J Murphy {\it et al} submitted to High Energy.
