MixIT: First spatially-resolved ion temperature measurement in ICF

Ion temperature is a key plasma variable and performance indicator in inertial confinement fusion. However, due to technological and physics limitations, all ion temperature measurements to date have been spatially integrated over the target assembly as viewed from a single line of sight. We present the methodology for, and results from, a proof-of-concept spatially-resolved ion temperature measurement conducted on ICF implosions, and path to a spatially-resolved, quantitative mix diagnostic.
