Analysis of cold divertor concepts by 2-D simulations
The most challenging issue in the design of future fusion experiments is a divertor concept which simultaneously provides tolerable power loading at the target plates and sufficiently large pumping rates. With respect to the target power load a reduction by at least one order of magnitude seems to be required. If this is to be achieved by upstream losses, one possibility is the proposed cold gas divertor concept, in which the energy is transferred mainly to the divertor side walls by CX-neutrals before reaching the target plate. This report discusses exploratory 2D simulations of divertors in present and future tokamaks (such as ITER). The main focus is on neutral gas effects rather than impurity radiation.
