Abstract : Plasmas are subject to many instabilities that make control of their components particularly difficult. It is well known that z-pinches are subject to Rayleigh-Taylor-like instabilities. This report analyzes MJ-level, 50 ns gas-puff z-pinches performed on the Saturn accelerator at Sandia National Laboratory with the magnetohydrodynamic codes Mach2 and Mach3. This analysis indicates that the uniformity of the pinch depends on the thickness of the initial gas-puff. Three-dimensional calculations suggest that modes with azimuthal asymmetry cause only modest changes to the radiative yield of fast z-pinches.
