Modelling of the emission spectra of tungsten plasma

NonLTE kinetics model for radiating plasma of multicharged ions is developed. The model takes into account the coupling between level occupancies and radiation transport. It allows to carry out the calculations for plasma configurations at arbitrary optical thickness. The calculations of tungsten emission spectra were made in a wide range of temperature and density ($30<T<150$ eV, $0.01<\rho<0.03$ g/cm$^3$). The codes THERMOS & BELINE were used for computation of nonLTE spectra of plane and cylindrical tungsten layers. At most important cases the calculations were verified as for line positions and also for more realistic geometry. The calculated spectra may be useful in the investigation of powerful wire array liners.
