Abstract :
We discuss two-dimensional magnetohydrodynamic simulations of the liner implosion, which model the development of Rayleigh-Taylor-like instability and interaction between the liner and PU glide planes. The simulations were conducted with variations in methodological parameters (random initial perturbations etc.) and in the glide plane shape. We found a glide plane shape that provides reliable electric contact with the liner during implosion and acceptable shape of the liner´s front surface before the impact without jets that are dangerous for diagnostics of the liner as an impactor.
