First Four Moments

We present recent results on radiative power losses of carbon and gold ions in fusion plasmas. Our approach is based on a detailed calculation, where the atomic database is provided by the MCDF code. A lineshape code, allowing for NLTE ionic populations, was adapted to the calculation of radiative power loss profiles. Because the calculation time is sometimes prohibitive, an alternative approach based on statistical distributions is proposed. This approach involves the first four moments of the radiative power losses. We have focused our attention on carbon and gold. The first element could be present in the ablator in some inertial confinement schemes. The second element is present in holraums and its X-ray emission contributes to the heating in inertial confinement fusion. Finally, opacity calculations are compared to measured transmission in aluminum ions.

Important Concern

AbstractImpurities being an important concern in tokamaks, spectroscopy plays a key role in their understanding. Techniques for the evaluation of concentrations, power losses and transport properties are surveyed, and a few developments are outlined.
