Spatially-Resolved Ion Temperature Measurement in ICF
ORAL
Abstract
Ion temperature is a fundamental plasma variable and key driver of ICF capsule performance. Further, studies have shown that cold fuel (DT ice) can be injected into the hotspot during implosion as a result of hydrodynamic effects such as fill tube jetting, and that this material can remain out of thermal equilibrium with the gas, leading to performance degradation. However existing ion temperature diagnostics provide only spatially integrated measurements, limiting understanding of these effects. We present design of, and results from, the first spatially-resolved ion temperature diagnostic developed for ICF.
