Dusty plasmas in a dc glow discharge

The striations proved to be a very useful tool to study various phenomena taking place in complex plasmas. In this work we present results of observations within a wide range of formations from an ordinary chain of several charged dust grains up to complex structures consisting of regions with different dusty plasma states. Plasma crystals, liquid-like structures with a short-range order and with a convective motion of dust particles, a development of dust waves have been studied at different plasma conditions and with spherical dust particles varying in size from 1.9 μm up to 63 μm. Experiments with 300 μm long cylindrical dust grains discovered the formation of the ordered structure similar to the liquid crystal
