Paper Abstract

We present new calculations on radiative power losses of carbon and gold. Both ions are involved in inertial confinement fusion. The first element could also be utilized in the walls of future TOKAMAK reactors such as ITER (International Thermonuclear Experimental Reactor) while the second is present in holraums and its X-ray emission contributes to the heating in ICF. Because argon impurities may be used in the fusion core, in order to diagnose the electron temperature, we have calculated the intensities of the He-β line and the Li-like Ar satellite lines. In fact, the intensity ratio depends on electron temperature. The effect of the plasma electric field on the line intensities is discussed. Our approach is based on a detailed line calculation in which the atomic database is provided by the MCDF code. Then a lineshape code allowing for NLTE ionic populations was adapted to the calculation of RPL profiles. Because the calculation time is sometimes prohibitive, a second approach, based on the first moments of the RPL, is investigated. This approach was used for extensive calculations on germanium.
