Abstract

Using the particle-in-cell method, the behavior of the dusty plasma under plasma fusion conditions of Tokomak's wall and the effect of the magnetic field on the process of dusty plasma particles were simulated and examined. The electric field is self-consistently solved from Poisson's equation. Electron-neutral elastic scattering, excitation, and ionization processes are modeled using Monte-Carlo collision method. The effect of the difference in the initial density of the plasma and the different magnetic field was simulated, and their results were compared together. The time to reach the saturation state and the amount of the saturated charge were obtained in the process of charging dust particles. It was observed that increasing the magnetic field does not necessarily mean an increase in the charge of dust particles or a decrease in the time to reach the saturation state. Finding the limit of this field, which certainly depends on the physical properties of the plasma, can be useful in some issues, for example, in plasma fusion conditions and labs. Some of the limitations of current theoretical models in the interaction of dust particles and plasma and the gap in the current empirical and theoretical approaches are described in the study of dust in fusion devices.
