A Survey of the Effect of Convergence Ratio with Low-Mode Drive Asymmetry on ICF Implosions
This series of slides begins by discussing convergence. It is seen that 3D hot spots develop more serious weak spots and are less tolerant of convergence. and that 3D perturbations are more damaging than 2D, and they become more so with increased convergence ratio. Then more results of computer simulations are shown. It is concluded that X-ray images are very different above and below 15 keV; small perturbations are likely puncture the capsule; fluid velocity significantly changes neutron inferred temperatures; and the thermodynamic temperature is changing drastically during the burn. The simulations predict effects large enough to potentially reconcile many apparent mysteries in the neutron and X-ray diagnostics.
