| 内容記述 | The Collisional Radiative(CR) approach has been widely used to analyze atomic processes in plasmas in non-thermodynamic equilibrium state (nLTE) to investigate their radiative property. For the application of laser-produced plasmas from light sources to fusion, coupled radiation hydrodynamics is of the interest, however, calculation of the CR-model taking complex atomic structure and atomic spectrum into account is still a part of the challenges. We have developed a calculation method based on a Markov Chain Monte-Carlo approach, which has enabled one to calculate the ionization balance of tungsten plasma for magnetic fusion with 1/100 less calculation time in comparison with those using the conventional method. We will also discuss the model describing the state of the plasma and its non-linear behavior taking these features of the radiation into account including possible applications of the model. | |||||
