Tailoring the radiation drive in dynamic hohlraums

Summary form only given, as follows. At the Sandia Z-facility, we have created a condition where the imploding pinch interacting with an inner target creates an intense radiation field or dynamic hohlraum environment. By tailoring the characteristics of this inner target the time-dependent temperature of the dynamic hohlraum can be varied. This control over the temperature history is necessary for performing inertial confinement fusion experiments near the Fermi degenerate isentrope. In this presentation we will show the effect of target Z and density profile on the radiation history produced. We will compare the experimental results with modeling of the temperature histories.
