Abstract :
Summary form only given. The calculations of tungsten emission spectra were carried out in a wide range of temperature and density (50 < T < 250 eV, 0.01 < p < 0.1 g/cm3). 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 position and also for more realistic geometry. The selfconsistent solution for an optically thick plasma layer was obtained by iterations as a result of consecutive refinement of the level equations for ion concentrations and equation of radiation transport. The calculations were carried out on the super computer MVS-1500M of the Interdepartmental Supercomputer Center of RAS.
