Hot electron preheat has been quantified in warm, directly driven inertial confinement fusion implosions on OMEGA and the National Ignition Facility (NIF), to support hydrodynamic scaling studies. These CH-shell experiments were designed be hydrodynamically equivalent, spanning a factor of 40 laser energy 3.4 spatial temporal scales, while preserving incident intensity 1015 W/cm2. Experiments w...
