Investigation of the trends of time-resolved inferred electron temperatures of fusion experiments at the National Ignition Facility

ORAL

Abstract

The electron temperature (Te) of the hot spot within the core of imploded inertial confinement fusion capsules is an effective indicator of implosion performance. Recently, an existing x-ray streak camera was upgraded at the National Ignition Facility to enable the inference of time-resolved Te of the hot core of controlled fusion imploded capsules. The upgrade involved a new dual slit and thick Titanium filters to isolate x-rays from specific energy regions. Herein, the trends of the inferred Te with measured performance parameters are investigated. In particular, inferred Te will be compared to measurements of neutron yield and ion temperatures as well as inferred levels of mix and hot spot bulk motion.
