Plasma Anisotropy Around an Infinite Chain of Dust Particles

Abstract

This paper presents a numerical model in which selfconsistent distributions of plasma space charge and potential are calculated in a proximity of the infinite chain consists of spherical dust particles. In the observed model, this chain is under an influence of an external electric field. The data obtained reveal a significant phenomenon: for the electric field of low intercity anisotropy around each individual dust particle raises lineary with the increase of external field strength. However, with further amplification of the external electric field this anisotropy start to decline, until it almost non-existent. Quantitatively this phenomenon is demonstrated through the dependency of the dipole moment of an “ion cloud – dust particle” system on the external electric field strength.
