Two-dimensional numerical simulation of imploding plasma liners

A computation analysis is performed to investigate 2D effects in imploding plasma liners. Some mechanisms degrade radiation output in the systems: the development of Rayleigh-Taylor (RT) type instabilities, “zippering” effect and instability of magnetized electrons current sheet. For the compressed double gas-puffs external axial magnetic field stabilizes short wavelength R-T instability. All these effects are studied numerically. The calculations were carried out using 2D three-temperature code TIGR-M. To predict liner shapes from supersonic gas puff injection, driven by time-dependent power pulse some calculations have been made. Dynamics of plasma in three-temperature MHD with Hall term is discussed.
