    "abstract": "The National Ignition Facility (NIF) technology is designed to drive\ndeuterium-tritium (DT) internal confinement fusion (ICF) targets to ignition\nusing indirect radiation from laser beam energy captured in a hohlraum.\nHydrodynamical instabilities at interfaces in the ICF capsule leading to mix\nbetween the DT fue l and the ablator shell material are of fundamental physical\ninterest and can affect the performance characteristics of the capsule. In this\nLetter we describe new radiochemical diagnostics for mix processes in ICF\ncapsules with plastic or Be (0.9%Cu) ablator shells. Reactions of high-energy\ntritons with shell material produce high-energy $\\beta$-emitters.\n  We show that mix between the DT fuel and the shell material enhances\nhigh-energy prompt beta emission from these reactions by more than an order of\nmagnitude over that expected in the absence of mix.",
