Asymmetry of wire-array Z-pinches at stagnation was investigated using four synchronized laser beams at the wavelength of 266 nm. These beams were spaced at 45° with respect to each other, allowing a full view of the pinch from four directions. The laser pulse duration was 0.2 ns, with a <0.1 ns temporal accuracy between the four channels. Strong asymmetry was found in Z pinches produced by implosion...
A series of Al/Mg nested wire array Z-pinch load experiments has been recently performed on the refurbished Z accelerator. The earlier comparison study of the results from ID and 2D radiation MHD simulations of the Sandia Z1907/1908 experiments [Y. K. Chong, et. al, APS09] has shown that, in addition to the substantial difference in the prediction capability of the ID and 2D models, the radiation...
Summary form only given. The paper presents simulation results of a Z-pinch experiment shot 51 using numerical code FLUX-rz, developed in STCP RFNC-VNIIEF. Calculations of an implosion process of a tungsten liner load were carried out with stationary uniform Eulerian grid in frameworks of a two-dimensional (in r-z plane) radiation magnetic hydrodynamics at self-consistent consideration of equations...
