Laser-induced-fluorescence measurement of thermal conductivity in warm dense matter generated by pulsed-power discharge

摘要

Thermal conductivity in warm dense matter isone of the interests for thermonuclear fusionscenarios. Alternative inertial confinement fusion,which is a fast ignition with applied magneticfield [1], has been considered to improvethe coupling efficiency. The target behavior ofthe fast ignition with applied magnetic field dependson the anisotropic thermal conductivity.The magnetic confinement fusion (MCF) [2] Upto now, the heat load on the divertor in previousMCF systems has been unreached parameter.Thus, to predict properties of the divertor underthese heat loads, several experiments have beenperformed using several methods[3-6]. To predictthe performance of the tungsten divertor inMCF, we should analyze not only metallurgicalproperties but also thermophysical properties ofablated tungsten...
