Development of comprehensive models for opacities and radiation transport for IFE systems.

Simulation and optimization of DPP hydrodynamics and radiation transport for EUV lithography devices

“…As shown earlier in [1,6,16,17], accounting for electrostatic and spin-orbit splitting of configurations and spectral lines considerably influences the dynamics of the energy balance in the plasma. A method of calculating the optical coefficients for high-Z plasma was developed and implemented in [16] by means of the collision-radiation equilibrium (CRE) model.…”

“…As previously shown [16], the details and the accuracy of calculating energy levels depend mainly on the method of implementing the J-splitting. The simplest way to account for splitting within the first order of the perturbation theory is to use the diagonal Lande correction [16,19].…”

“…A method of calculating the optical coefficients for high-Z plasma was developed and implemented in [16] by means of the collision-radiation equilibrium (CRE) model. The important feature of this method is the joint use of HFS atomic data and Racah techniques of angular moments.…”

“…The simplest way to account for splitting within the first order of the perturbation theory is to use the diagonal Lande correction [16,19]. Nevertheless, xenon ions are characterized by the intermediate coupling, when electrostatic and spin-orbit splittings are comparable.…”

Calculation of tin atomic data and plasma properties.

“…Knowing that the total transition strength is unchanged, the radiation in strong lines may be collapsed for a dense plasma, while the radiation in weak lines stays optically transparent. The line splitting may dramatically influence the total hydrodynamic behavior of a plasma through the radiation transport mechanism [5].…”
