Slowing down of charged particles in dusty plasmas with pawer-law kappa-distributions

Abstract

We study the slowing down of particle beams passing through the dusty plasma with power-law kappa-distributions. Three plasma components, electrons, ions and dust particles, can have different kappa-parameter. We derive the deceleration factor (the velocity moment equation) and the slowing down time of a test particle, and numerically study the slowing down properties of an electron beam, a proton beam and a dust particle beam, respectively, in the kappa-distributed dusty plasma. We show that the slowing down properties of particle beams depend strongly on the kappa-parameters of the plasma components, and the dust component plays a dominant role in the slowing down. And the slowing down also depends on mass and charge of the dust particles in the dusty plasma. More detailed results are shown in 17 numerical graphs.
