Research Abstract

We investigate the mechanism of formation of the inhomogeneous structure in laser produced plasmas and discharge plasmas, by taking the phase transition processes into account, which originate from atomic and radiative properties of plasmas. We develop a detailed atomic model of tungsten, which is interested in fusion plasmas. The size of the model is parameterized, and accuracy of the calculation of mean charge and radiative power loss is improved by sensitivity studies and benchmark calculations. We also investigate percolation transition in discharge plasmas. We investigate development of discharge in SF6 based on its material properties such as ionization and attachment coefficient to reproduce experimental observations from initial partial discharge to later growth of the stepped leader to cause breakdown. By combining both atomic model, radiative transfer model and phase transition model understanding of structure formation in the plasmas will be improved.
