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

The electron temperature (T_e) 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 T_e 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 T_e with measured performance parameters are investigated. In particular, inferred T_e will be compared to measurements of neutron yield and ion temperatures as well as inferred levels of mix and hot spot bulk motion.
