The universe is permeated by magnetic fields, with strengths ranging from afemtogauss in the voids between the filaments of galaxy clusters to severalteragauss in black holes and neutron stars. The standard model behindcosmological magnetic fields is the nonlinear amplification of seed fields viaturbulent dynamo to the values observed. We have conceived experiments that aimto demonstrate and study the turbulent dynamo mechanism in the laboratory. Herewe describe the design of these experiments through simulation campaigns usingFLASH, a highly capable radiation magnetohydrodynamics code that we havedeveloped, and large-scale three-dimensional simulations on the Mirasupercomputer at Argonne National Laboratory. The simulation results indicatethat the experimental platform may be capable of reaching a turbulent plasmastate and study dynamo amplification. We validate and compare our numericalresults with a small subset of experimental data using synthetic diagnostics.
