Abstract :
Summary form only given. Magnetized target fusion (MTF) relies on magnetic field suppression of thermal transport to achieve fusion conditions at relatively low driver power. One method proposed for MTF uses an imploding liner which starts at solid density to compress a hot magnetized plasma. Analytic methods and one and two dimensional magnetohydrodynamic simulations are being used to study this plasma liner compression approach. Plasma from the liner walls represents a contaminant that can increase radiation losses and lower plasma temperatures below desired values. As part of this effort are we are investigating the generation and evolution of such plasmas. Energy input to the liner from thermal conduction and joule heating from both the magnetized plasma and the driving magnetic field are under study to determine their contributions to the production of contaminant and the interaction of these plasmas with the hot fusion plasma. Results from these ongoing calculations will be presented.
