SUMMARY:FLASH simulations of a magnetized turbulence experiment at the
  National Ignition Facility\, Plasma Physics (Physics/ECE/NE 922) Semi
 nar\, Dr. Scott Feister\,  Flash Center for Computational Science\, Un
 iversity of Chicago
DESCRIPTION:The National Ignition Facility (NIF)\, the world’s most 
 energetic laser\, is more than an inertial confinement fusion platform
  – it can drive extreme plasma conditions for laboratory astrophysic
 s. The University of Chicago and its international team of collaborato
 rs won allocation of several NIF shots\, spaced over a few years\, to 
 study the development of magnetized turbulence and turbulent dynamo. B
 y giving validated simulations a central role in the experimental desi
 gn process\, we have endeavored to "not throw away our shot." The 3D M
 HD code FLASH was validated in a range of smaller experiments\, then i
 t was used to simulate our experimental ideas from start (laser intera
 ction) to finish (plasma diagnostics). We have replicated plasma diagn
 ostics within FLASH to make one-to-one comparisons with experimental d
 ata\, and make choices about diagnostic timings and exposures. Our sim
 ulations have also informed many aspects of the experimental target de
 sign and laser drive as implemented at NIF. These simulations show Bie
 rmann battery magnetic fields seeded in the laser interaction and ampl
 ified in a central\, highly-turbulent dynamo region.
