INTERACTION OF A PLASMA-FLOW WITH A SOLID TARGET

A physical-mathematical model of the interaction between a plasma flow and a solid target is presented. Gasdynamic equations, along with equ ations for kinetics of the ion population and equations for line and c ontinuum-radiation transport are solved self-consistently. Processes o f target destruction and evaporation are also considered. A comparison is made of the calculated results with the experimental data obtained for a graphite target. Losses due to line-radiation transport are sho wn to be about 50% in the plasma energy balance. Predictions are made for the characteristics of the plasma, which can be obtained with a Be target in the 2MK-200 device and with a graphite target under conditi ons similar to those expected in the disruption regimes in the ITER de vice.
