Measuring the Effect of Heterogeneous Mix on Thermonuclear Burn in the Marble Campaign Using an Argon/Tritium Fill Gas
Abstract
The Marble campaign on NIF quantifies the effect of heterogeneous mix on thermonuclear burn for comparison to a probability distribution function (PDF) burn model. 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.
