Join us for a seminar with Dr. Carolyn C. Kuranz, Associate Research Scientist at the University of Michigan, titled “Hydrodynamic Instability and Radiation Hydrodynamics Experiments in High-energy-density Plasmas.”
The seminar will begin at 3pm ET on February 2, 2021. It will be held via Microsoft Teams.
Abstract: Hydrodynamic instabilities can occur during multiple phases of inertial confinement fusion experiments causing unwanted hydrodynamic mixing, limiting gain and stymie fusion ignition. Therefore, it is important to fundamentally understand these instabilities through experiments, simulations, and theory. Using high-energy lasers, we can create strong pressure and velocity gradients that drive hydrodynamic instabilities under high-energy-density conditions. Also, strong radiation fields can affect hydrodynamic evolution. I will present a study of the evolution of hydrodynamic instabilities and radiative shocks, specifically the suppression of Kelvin-Helmholtz growth due to compressible effects, and the ablative stabilization of the Rayleigh-Taylor instability. We use the x-ray radiography technique to create a 2D image of instability growth and observe the evolution of these processes.
