具有Pawer律κ分布的尘埃等离子体中带电粒子的慢化
Slowing down of charged particles in dusty plasmas with pawer-law kappa-distributions
摘要：
本文研究了粒子束通过具有幂律κ分布的尘埃等离子体时的慢化。三种等离子体成分，电子，离子和尘埃粒子，可以有不同的卡帕参数。导出了粒子的减速因子（速度矩方程）和减速时间，并分别数值研究了电子束、质子束和尘埃粒子束在κ分布尘埃等离子体中的减速特性.结果表明，粒子束的慢化特性强烈依赖于等离子体组分的kappa参数，尘埃组分在粒子束慢化中起主导作用。而这种减速也取决于尘埃等离子体中尘埃粒子的质量和电荷。更详细的结果显示在17个数值图中。
英文摘要：
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.
