Dust formation and growth in plasmas are in most cases continuous cyclic phenomena. We show that the growth of new dust generations takes place in a dust-free region, usually called a void, in the dust cloud. The three-step process of new dust generation is detailed thanks to the correlation between electrical, optical, and ex situ diagnostics. The strong inhomogeneity of both the plasma and the dust cloud during this process is underlined.
在大多数情况下,等离子体中的尘埃形成和生长是连续的循环现象。我们表明,新尘埃世代的生长发生在尘埃云中一个通常称为空隙的无尘埃区域。由于电学、光学和非原位诊断之间的相关性,详细阐述了新尘埃产生的三步过程。在此过程中强调了等离子体和尘埃云两者的强烈不均匀性。
